We’re being asked to determine the effect of temperature on the rate of reaction.

We will base our answer on collision theory and Arrhenius concept. In **collision theory**, we look at all the different factors that have to be taken into account whenever reactant molecules collide in order for products to be successfully created.

This involves the **Arrhenius Equation** shown below:

$\overline{){\mathbf{k}}{\mathbf{}}{\mathbf{=}}{\mathbf{A}}{\mathbf{\xb7}}{{\mathbf{e}}}^{\frac{\mathbf{-}{\mathbf{E}}_{\mathbf{a}}}{\mathbf{RT}}}}$

A = Frequency Factor

Ea = Energy of Activation

R = Gas Constant = 8.314 J/(mol∙K)

T = Temperature

In general, as the temperature increases, the rate of a chemical reaction:

A. increase due to an increased activation energy

B. increases only for an endothermic reaction

C. increases because bonds are weakened

D. increases due to a greater number of effective collisions

E. is not changed
