The reaction

H2(g) + I2(g) ----> 2HI(g)

proceeds via a two-step mechanism in which the rate law for the rate-determining step is rate= k[H2][I]2. Write the mechanism for the reaction.

Step 1:

Step 2:

Now rewrite the rate law using only reactant concentrations. Use square brackets notation.

rate=

identify any intermediates in the mechanism

what is the rate law according to the mechanism


consider the following reaction: H2 + 2IBr -> I2 + 2HBr

a plausible mechanism for the reaction is as follows:

step1: H2 + IBr -> HI + HBr

step2: HI + IBr -> I2 + HBr

Step 1 is the rate determining step because it has the higher activiation energy in a graph.

If you measure the inital concentrations of H2 and IBr to be 0.84M and 0.66M, respectively, and the rate of formation of HBr is .0045M/s, what is the value of the rate constant?
