Question 1

The isomerization reaction, CH3NC → CH3CN, is first order and the rate constant is equal to 0.46 s-1 at 600 K. What is the concentration of CH3NC after 0.20 minutes if the initial concentration is 0.30 mol L-1?
◦ 2.7 × 10-1 mol L-1
◦ 2.7 × 10-3 mol L-1
◦ 1.2 × 10-3 mol L-1
◦ 1.2 × 10-1 mol L-1

Question 2

The following reaction is first order, C2H6 → 2CH3. If the rate constant is equal to 5.5 × 10-4 s-1 at 1000 K, how long will it take for 0.35 mol of C2H6 in a 1.00 L container to decrease to 0.20 mol in the same container?
◦ 53 min
◦ 17 min
◦ 65 min
◦ 4.5 min
