1) The rate law for the reaction (A + 3B C + 2D) was found to be () = [][] 2 = 2.7 mol/dm3 s. What are the units of kr when the concentrations are in mol/dm3 ? Determine (i) the rate of formation of C and D and (ii) the rate of consumption of A and B.

2) In a study of the enzyme-catalyzed oxidation of ethanol, the molar concentration of ethanol decreased in a first order reaction from 220 mmol/dm3 to 56 mmol/dm3 in 1.22 104 s. What is the rate constant of the reaction?

please solve in Detail Thanks.
