This essay rate of reaction is available for you on essays24com search term papers, college essay examples and free essays on essays24com - full papers database to find out how different concentrations change the rate of reaction.

Rates of reaction the rate of a reaction can be measured by the rate at which a reactant is used up, or the rate at which a product is formed the temperature, concentration, pressure of reacting gases, surface area of reacting solids, and the use of catalysts, are all factors which affect the rate of a reaction. So the rate of reaction, the average rate of reaction, would be equal to 002 divided by 2, which is 001 molar per second so that's our average rate of reaction from time is equal to 0 to time is equal to 2 seconds. Reaction rate is the change in concentration of a reactant or product per unit time this means that you need to find the rate by formula: [a] at time t2- [a] at t1 / t2- t1 where [a] is concentration of the product or reactant note that rates are not constant an this formula gives you average rate if you use final.
