For a reaction, consider the plot of  versus  given in the figure. If the rate constant of this reaction at 400 K is , then the rate constant at 500 K is:

Canvas Classes · Accepted Answer

From the graph, the slope of  vs  can be read. The slope .

Reading the graph: when  decreases from  to  (i.e.,  increases from 400 to 500 K),  increases by approximately 2.303 (one log unit).

This means  increases by a factor of 10:
