Question

Which of the following are correct for zero-order reactions? Check all that apply. View Available Hint(s) Check all that apply.

The concentration of the reactants changes nonlinearly.

A higher concentration of reactants will not speed up the reaction.

The rate of reaction does not equal the rate constant.

The units for the rate constant and the rate of reaction are the same.

A zero-order reaction slows down as the reaction proceeds

Part B

In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 1.70 molL1 and its rate constant (k) is 0.0014 molL1s1 . Determine the rate of reaction if it follows a zero-order reaction mechanism.

Explanation / Answer

for zero order of reaction

rate = K[A]0         but zero order of reaction doesnot depends on initial concentration

rate = k

So for zero order reaction units of rate constant and rate of the reaction are the same

units= Ms-1.

part-B

[A]0= 1.70mol.L--1

K = 0.00014 mol.L-1s-1

for zero order of reaction

rate= K[A]0

rate of th reaction = 0.0014

rate of the reaction= 0.0014mol-L-1s-1

because the zero order of the reaction doesnot depends onthe initil concentration of the reactant.
