a) Consider the following reaction: A + 2B → 3 C Keq= 2.37x106

What is the value of the rate constant if the reaction is multipled by 3? Express your answer in scientific notation.   

b) Consider the following reaction: A + 2B → 3 C   Keq= 4.05x106

What is the value of the rate constand if the reaction is reversed? Express your answer in scientific notation.

(can someone show me the steps with the answer because im still unclear on the formulas and how to use them with this unit. please and thank you)

Expert Solution

a) Consider the following reaction: A + 2B → 3 C Keq= 2.37x106

What is the value of the rate constant if the reaction is multipled by 3? Express your answer in scientific notation.   

Solution :- when the reaction is multiplied by 3 then rate constant is also increases by factor 3

So

New rate constant K = (keq)^3

                            = (2.37*10^6)^3

                           = 1.33*10^19

b) Consider the following reaction: A + 2B → 3 C   Keq= 4.05x106

What is the value of the rate constand if the reaction is reversed? Express your answer in scientific notation.

Solution :- when the reaction is reversed then rate constant is inversed therefore

New rate constant K = 1/ keq

                                      = 1 / 4.05*10^6

                                     = 2.47*10^-7
