question 36

Multiple Choice

The gas-phase reaction CH₃NC → CH₃CN has been studied in a closed vessel, and the rate equation was found to be: Rate = -Δ[CH₃NC]/Δt = 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
