Question

There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: k=Ae−Ea/RT, where k is the rate constant, A is the frequency factor, Ea is the activation energy, R=8.314 J mol−1 K−1 is the gas constant, and T is the absolute temperature.

A certain reaction has an activation energy of 63.0 kJ mol−1 and a frequency factor of A1= 3.20×10¹² L mol−1 s−1. What is the rate constant, k, of this reaction at 29.0∘C?

Answer 1

Arhenius equation was found to find the feasibility of reaction

There are basically 2 factors to find feasibility of reaction

(1) the reactant molecules collide in proper orientaion represented by frequency factor

(2) all molecules could cross the energy barrier represented by exponential factor

And both multiplied tells us how feasible is the reaction
