Question

For the reaction A + B + 2 C rightarrow 3 D at 25 degree C the following initial rate data were obtained: Write the rate law expression for the reaction. What is a plausible rate-determining step in the mechanism of this reaction? What is the numerical value for k, the rate constant for this reaction? (Be careful of units) In Experiment 1, what would the rate of the reaction be when exactly 1/2 of the A present initially has been consumed? In experiment 2, what is the maximum concentration obtainable for D? (Assume that the volume remains constant.) In experiment 4, when the reaction has proceeded to completion, which reactant or reactants if any, and in what concentration, remain unconsumed?

Explanation / Answer

e) 1 mole of A reacts with 2 moles of C to give 3 moles of D

0.3 moles of A reacts wtih 0.6 moles of B to give rise to 0.9 moles of D

So concentration of D =0.9M

f) since B is not participating in the reaction all the concentrations of B given in the respective experiments reamin un reacted.
