A student made an Arrhenius graph of Ln(k1/k2) versus 1/T (K-1). However she erroneously plotted 1/T on the Y axis instead of plotting 1/T on the X axis. She displayed the linear trendline to her graph in Excel. The equation of the trendline was Y = -0.000084*X  - 0.047. What was the value of the slope had she plotted the data correctly?
