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 formula: t1/2 = ln(2)/k where k is the rate constant. From the rate law given, we can see that the reaction follows first-order kinetics. Therefore, we can use the given rate constant (k) to calculate the half-life. k = (1300 s¯¹) t1/2 = ln(2)/k = ln(2)/(1300 s¯¹) = 5.3 F1F1F1S1F1F1F10 10¯⁴ s So, the correct answer is B.
