Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

CHAPTER 4 (MANKIW) INFLATION RATES AND INTEREST RATES: THE FISHER EQUATION NOTES by: Chadia Mathurin Economists differentiate between real and nominal interest rates where: real interest: is defined as the increase or decrease in a consumer’s purchasing power experienced as a result of changes in the interest rate. nominal interest: is defined as the interest payed by the bank. Let: i denote the nominal interest rate r the real interest rate pi ‚ the inflation rate The equation for the

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

1. Suppose you discover a treasure chest of RM10 billion in cash a. Is this a real or financial asset? Answer: Yes. 10 billion cash is the financial asset. This is because financial assets only obtain its monetary value from a contractual agreement of what it represents. In contrast‚ real asset itself has the physical value. b. Is society any richer for the discovery? Answer: No. This is because the cash does not contribute to the productive capacity of the economy. c. Are you wealthier

Effects of Raising Interest Rates If a central bank increases the base rate‚ this tends to increase all major interest rates in the economy. This means interest rates for both savers and borrowers will increase. Higher interest rates will have various economic effects: 1. Increases the cost of borrowing. Interest payments on credit cards and loans will be more expensive. Therefore this discourages people from borrowing and saving. People who already have loans will have less disposable income

bonds‚ maturing in 7 years‚ pay 8% interest on a $1‚000 face value. However‚ interest is paid semi-annually. If your required rate of return is 10%‚ what is the value of the bond? How would your answer change if the interest were paid annually? 7) Sharp Co. bonds are selling in the market for $1‚045. These 15 year bonds pay 7% interest annually on a $1‚000 par value. If they are purchased at the market price‚ what is the expected rate of return? 8) You own a bond that pays $100 in annual interest

1.Female Literacy a)Main observation: countries with low fertility rates have high literacy rates and vice versa. Tthe fertility rate of a country is thus inversely proportional to female literacy rate. At the literacy rate of 60%‚ fertility rate is about 7.72. At the litaracy rate of 100%‚ fertility rate is about 1.21. b)Cost of having a baby explicit short term: Birth and pre-natal expenses long term: Housing Food Education Transport Clothing Healthcare

Free exchange Savers’ lament The complex effects of low interest rates on consumption and investment Dec 1st 2012 | from The Economist print edition WHEN interest rates hit double digits in the late 1970s‚ house-builders sent planks of wood to the Federal Reserve in protest. With rates stuck near zero‚ the protests now come from the opposite direction. The retired complain of a “war on savings”. The Fed cut rates to current levels at the end of 2008 and has promised to keep them there until

Unemployment Rate by Race/Ethnicity Marcel Palomo ECON 201 17 MAR 13 Professor Mills Unemployment Rate by Race/Ethnicity There has always been a difference between unemployment rate from the four major ethnic groups which are White‚ Black or African‚ Hispanic or Latino‚ and Asian My paper will examine why there is such diversity in amongst these groups. People of Asian descent have the lowest unemployment rates compared to the other four groups‚ while unemployment among Hispanics
