B2H6k12BH3B2H6+BH3k2B3H6+HH+Hk3H2 a. Based on this proposed reaction mechanism, derive the rate law expression for the rate of consumption of B2H6 in terms of measurable quantities and constants. For full credit, state the assumptions applied in the derivation and simplify the expression appropriately. (Note that part b of this problem is on the next page.) b. The derivation of a rate law from a hypothesized mechanism ultimately needs to be verified by experimental data. The data for the disappearance of B2H6 in a batch reactor is given below. This reaction is liquid-phase and isothermal. Based on your derived rate law from part (a), use the Integral Method to determine if this data is consistent with your rate law. Justify your answer with calculations and explanations of your method. Determine the value of the rate constant k1. (If you cannot solve part a, then make assumptions to answer this question. State assumptions.)
