Question

1.) In order to determine the value of the activation energy for a particular chemical reaction,

A. two experiments must be performed at the same temperature, but with different concentrations of each reactant B. the reaction mechanism must be experimentally verified. C. the rate law must be determined. D. two experiments must be performed at different temperatures, but with identical concentrations of each reactant E. the reaction must be a first order reaction.

2.) The activation energy in the Arrhenius equation can best be described as
A. a factor which corrects for the conversion between degrees K and degrees C. B. the amount of energy released by colliding reactant molecules when they form products. C. the base of the natural logarithm system. D. the frequency with which reactant molecules collide with the proper orientation to react at a specific concentration. E. the minimum amount of energy which colliding reactant molecules must have to form products.

Explanation / Answer

1) Answer:D

two experiments must be performed at different temperatures, but with identical concentrations of each reactant.

So that rate constant can be determined and using

2) Answer:  E. the minimum amount of energy which colliding reactant molecules must have to form products.

This is by definition
