Activation energy and rate of reaction

The activation energy of a certain reaction is 76.7 kj/mol. How many times faster will the reaction occur at 62 degrees C than at 5 degrees C?

Solution Preview

The Arrhenius equation states that
k= A e ^ (-E act /RT)
k is the rate constant
A is frequency factor
E act= activation energy= 76.7 kJ/mol
R=universal gas constant

At two temperatures T1 and ...

Solution Summary

The solution calculates the speed of reaction.
