FREE Expert Solution

We’re being asked to calculate the rate law and the value of the rate constant (k) based on the reaction and data given.

Given reaction: CH3Cl(g) + 3 Cl2(g) → CCl4(g) + 3 HCl(g)

Recall that the rate law only focuses on the reactant concentrations and has a general form of:

rate law=kAxBy

k = rate constant
A & B = reactants
x & y = reactant orders


We’re going to calculate the rate law and the rate constant using the following steps:
