The rate law for the rearrangement of CH₃NC to CH₃CN at 800 K is Rate = (1300 s^-1)[CH₃NC]. What is the half-life for this reaction?

Question

Quizplus · Accepted Answer

The half-life of a first-order reaction can be calculated using the equation: t1/2 = ln(2)/k where k is the rate constant. In this case, the rate law is: Rate = k[CH₃NC] Comparing this with the standard form of the rate law, we can see that the rate constant is: k = 1300 s^-1 Substituting this into the equation for half-life, we get: t1/2 = ln(2)/k = ln(2)/(1300 s^-1) ≈ 5.3 × 10^-4 s Therefore, the correct answer is B.
