Question

1. in the graph to the right, an increase in temperature results in * the effect of temperature on the rate of a chemical reaction relative reaction rate temperature a. a decrease in the required activation energy. b. an increase in reaction rate. c. a decrease in the rate of reaction. d. an increase in both the reaction rate and activation energy

Explanation:

Step1: Analyze the graph

The graph shows that as temperature increases, the relative reaction rate increases.

Step2: Recall chemical - reaction concepts

Activation energy is a constant for a particular reaction and is not affected by temperature changes (it can be affected by catalysts). An increase in temperature provides more kinetic energy to reactant molecules, increasing the frequency of effective collisions and thus the reaction rate.

Answer:

B. An increase in reaction rate.
