Problem: In general, as the temperature increases, the rate of a chemical reaction: A. increase due to an increased activation energyB. increases only for an endothermic reactionC. increases because bonds are weakenedD. increases due to a greater number of effective collisionsE. is not changed

FREE Expert Solution

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:

k =A·e-EaRT

A = Frequency Factor
Ea = Energy of Activation
R = Gas Constant = 8.314 J/(mol∙K)
T = Temperature
