Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

In order to determine a rate law we need to find the values of the exponents n, m, and p, and the value of the rate constant, k. If we are given the reaction orders for a reaction, we have the values of the coefficients we need to write the rate law.Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes...

Step 1: Convert temperatures from degrees Celsius to Kelvin. T = degrees Celsius 273.15. T1 = 3 273.15. ...
Step 2 - Find Ea ln(k2/k1) = Ea/R x (1/T1 - 1/T2) ln(7.1 x 10-2/8.9 x 10-3) = Ea/8.3145 J/K·mol x (1/276.15 K - 1/308.15 K) ...
Answer: The activation energy for this reaction is 4.59 x 104 J/mol or 45.9 kJ/mol.

The rate law is a differential equation, meaning that it describes the change in concentration of reactant(s) per change in time. Using calculus, the rate law can be integrated to obtain an integrated rate equation that links concentrations of reactants or products with time directly.
