Question 1

The isomerization of cyclopropane to propene follows first-order kinetics.
         
At 700 K, the rate constant for this reaction is 6.2 × 10–4 min–1.  How many minutes are required for 10.0% of a sample of cyclopropane to isomerize to propene?
◦ 16,100 min
◦ 170 min
◦ 3,710 min
◦ 1.43 × 10–3 min
◦ 1,120 min

Question 2

The isomerization of methyl isocyanide, CH3NC → CH3CN, follows first-order kinetics. The half-lives were found to be 161 min at 199°C and 12.5 min at 230°C.  Calculate the activation energy for this reaction.
◦ 6.17 × 10–3 kJ/mol
◦ 31.4 kJ/mol
◦ 78.2 kJ/mol
◦ 124 kJ/mol
◦ 163 kJ/mol
