MCQ

Choose the most correct option.

Rate law for the reaction, $\ce{2NO + Cl2 -> 2NOCl}$ is rate = k[NO2]2[Cl2]. Thus of k would increase with _____________.

#### Options

• increase in temperature

• increase of concentration of NO

• increase of concentration of Cl2

• increase of concentrations of both Cl2 and NO

#### Solution

Rate law for the reaction, $\ce{2NO + Cl2 -> 2NOCl}$ is rate = k[NO2]2[Cl2]. Thus of k would increase with increase in temperature.

Is there an error in this question or solution?
