Solution: The accompanying graph shows plots of ln k versus 1/T for two different reactions. The plots have been extrapolated to the y-intercepts. Which reaction has the larger value for Ea?

Problem

The accompanying graph shows plots of ln k versus 1/T for two different reactions. The plots have been extrapolated to the y-intercepts. A graph of natural log k versus 1 divided by T (both unscaled) shows a red and blue line that both decline linearly. The red line starts higher on the y-axis and its slope is flatter.

Which reaction has the larger value for Ea?
