Chem 101 Homework 8: Kinetics Question 5.f

Question

Data is collected for the gas phase reaction 2 A + B + 3 C → Products at 470 K. Use the rate law Rate = k[B]²[C]. What is the value of the rate constant at 470 K for this reaction?

Answer 1

Zero order in A ( compare trials 2 and 3)

Second order in B (compare trials 3 and 4)

First order in C (compare trials 1 and 2)

Rate = k[B]²[C]

.0357 = k(0.2)²(0.15)

solve for k and units will be M^-2min^-1
