19. For the reaction, A+2B ->C+2D, some measurements of the initial rate of reaction at varying concentration gave the following data. Use these data to write the rate law. Experiment Rate (mol L-1 s-1 ) [A] 0.100 0.200 0.000360 0.150 0.200 0.000540 0.150 0.250 0.001055 [B] a. the rate law is therefore: rate k[A] B b. the rate law is therefore: rate k[A[B] c. the rate law is therefore: rate kiAF[B d. the rate law is therefore: rate k[A][B] e. the rate law is therefore: rate k[A][B]

Solution

Option (b) is correct.As the rate values clearly indicstes that the fastest rate is when the conc of B is nearly twice to A that is rate depends upon 2 powers of B and 1 power of A.

The third rate value .001055 clearly indicates this condition.
