lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams of

The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of

In some countries the United States dollar is worth more than that countries currency‚ while in other countries the U.S. dollar is worth less. The exchange rate fluctuates on a continuous base which makes the term “funny money” more realistic each day. The purpose of this paper

QUESTION ONE WHY MULTINATIONALS FIRMS MUST ASSESS THE BUSINESS ENVIRONMENT OF COUNTRIES THEY OPERATE AND INTEND TO OPERATE IN. Multinational Corporation/Firm is a business that produces or distributes products or services in one or more foreign countries by establishing a branch or affiliate there. These multinational Corporations operate in a complex business environment. Cultural‚ social‚ economic‚ political and technological systems vary from country to country. In order to operate successfully

concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react

According to human resource experts‚ the average attrition rate is projected to grow at 31 per cent in Indian firms in the April-June quarter‚ a rise of 9-10 per cent from the preceding quarter (January-March). SPECIAL: Best companies to work for India In the April-June quarter of 2011-12‚ the average attrition rate was 27 per cent. Generally‚ employees would have received their annual appraisals during the April-June period and those not happy with their performance review or salary hikes

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important

Examine the main trends in the birth and death rates in the UK since 1900 As the population of a country increases‚ there will be certain factors affecting the people of that country; the birth rate‚ and the death rate are two of the major demographic trends. Since 1900 the UK has changed greatly‚ as has the demography of the country. The Birth rate - the number of live births per 1000 of the population per year originally was fairly high due to the fact that child labour was legal in Victorian
