The gas-phase reaction C: RateH3NC = CH3CN has been studied in a closed vessel, and the rate equation was found to be: Rate = -delta [CH3NC]/delta t = k[CH3NC]. Which one of the folowing actions is least likely to cause a change in the rate of the reaction?
a. Lowering the temp.
b. adding a catalyst
c. using a larger initial amount of CH3NC in the same vessel
d. using a bigger vessel, but the same initial amount of CH3NC
e. continuously removing CH3CN as it is formed.
