I need help with part b which is

Determine the rate constant for the reaction at 1500°C.

The answer should be ___________ M^-x S^-1

Answer 1

Similarly from experiment 2, we get :

k = 0.0609/ (0.212)² * (0.272) M^-2s^-1 = 4.98 M^-2s^-1

from experiment 3, we get :k = 0.480/ (0.424)² * (0.544) M^-2s^-1 = 4.91 M^-2s^-1

from experiment 4, we get :k = 1.93 / (0.848)² * (0.544) M^-2s^-1 = 4.93 M^-2s^-1

Average value of k = (4.96 + 4.98+ 4.91+4.93)/4 M^-2s^-1 = 4.95 M^-2s^-1
