RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Folio piece-short story I had no choice it was either him or the damnation of my people. My hands were quivering with fear‚ sweat was dripping from my forehead as I made the decision to kill him. The man that sat in my barber shop chair had killed 14 of my friends and had death on his mind‚ the devil was at work in this man. Tension was rising‚ I walked across the empty room sharpening the blade of my silver razor‚ I continued to shave his beard as any good barber would have‚ each stroke smother

’Exchange Rate’ The price of a nation’s currency in terms of another currency. An exchange rate thus has two components‚ the domestic currency and a foreign currency‚ and can be quoted either directly or indirectly. In a direct quotation‚ the price of a unit of foreign currency is expressed in terms of the domestic currency. In an indirect quotation‚ the price of a unit of domestic currency is expressed in terms of the foreign currency. An exchange rate that does not have the domestic currency

Labor rate variance is the difference between the actual labor rate and the applied overhead rate (standard rate multiplied by the number of actual hours worked). Consider this and respond to the following: • "Our workers are all under labor contracts. Therefore‚ our labor rate variance is bound to be zero." Do you agree or disagree that the labor rate variance will be zero if all workers are under labor contracts? Explain giving reasons. The concept of labor rate variance and its application

31) QUALITY OF DRIED FOODS AND DETERIORATIVE REACTIONS DURING DRYING Consumer demand has increased for processed products that keep more of their original characteristics. In industrial terms‚ this requires the development of operations that minimize the adverse effects of processing. The effect of food processing on finished product quality ultimately determines the usefulness and commercial viability of that unit process operation. In the particular case of food drying this indicates that loss

What factors might contribute to a low or high growth rates in a country? There are three categories of factors that contribute to a low or high growth rates. These categories are the demand factor‚ the efficiency factor‚ and supply factors. Government spending or exports can lead to a higher to aggregate demand and higher economic growth. “Economic growth requires increases in total spending to realize the output gain made available by increased production capacity” (McConnell‚ 2012‚ p. 513)

clear that the crime rate is increasing in our country. More and more crimes have happened for a long time. People are feeling unsecured with the crime situation and the fear of being a victim to keep increasing. The government has been taken some action to overcome these problems. However‚ it is not enough to reduce all incidences of crime. There are several steps or measures which can be taken to reduce the crime rate in Malaysia. First of all‚ it has to enact laws which impose stiffer penalties

The unemployment rate An unemployed person is one who is able and willing to work yet is unable to find a job. The unemployment rate is the number of unemployed workers divided by the total civilian labor force‚ which includes both the unemployed and those with jobs. Measuring the number of unemployed workers actually seeking work is very difficult‚ but there exists several different methods to do so. Each method has its own biases and the different systems that make comparing unemployment
