for a given reaction, the rate constant k was measured as a function of temperature t. from the data, a ln(k) versus \frac{1}{t} plot was generated, and the data was fit to a straight line. if the activation energy for the reaction is 16.11 \frac{kj}{mol} , then what is the slope (in joules) of the ln(k) versus \frac{1}{t} plot?
