In the gas phase at 500. C, cyclopropane reacts to form propene in a first-order reaction. The figure shows the natural logarithm of the concentration of cyclopropane (in mol/L) plotted versus time. 
a. Explain how this plot confirms that the reaction is first order.
B) Calculate the first-order rate constant, k.
C) Determine the initial concentration of cyclopropane in this experiment.
