The reaction

A + B + C → ABC

is zero order with respect to one reactant, first order with respect to another reactant and second order with respect to another reactant.

a. i. Explain what is meant by the term order of reaction with respect to a given reactant.

ii. Use the data in the table below to deduce the order with respect to each of the reactants, A, B and c.

b. i. Write the rate equation for this reaction.

ii. State the overall order of the reaction.

iii. Calculate the value of the rate constant using experiment 6. Include the units in you  answer.

c. Suggest a possible mechanism consistent with the rate equation you have proposed and the chemical equation A + B + C → ABC
