Question

In a chemistry experiment that measures the kinetics of reaction at different temperatures, the activation energy of the reaction can be measured by finding the slope of the line in a ln k vs. 1/T plot. The following data are gathered from this kinetics experiment:

1. Construct a scatterplot of the ln k versus 1/T and fit a least-square regression line using the graph paper below.
1. Compute the correlation coefficient between ln k and 1/T.
1. Write statement that interprets the correlation coefficient in the best way.
