(P Various Sections) the Gas-Phase Reaction Has Been Studied $\Delta$

Multiple Choice

(p. Various sections) The gas-phase reaction 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 following actions is least likely to cause a change in the rate of the reaction?

A) lowering the temperature
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
