Question

The rate of the reaction,
$2NO+C{l}_2\to 2NOCl$ is given by the rate equation, $\text{Rate}=k\left[NO{]}^2\right[C{l}_2]$. The value of the rate constant can be increased by

• A. Increasing the temperature
• B. Increasing the concentration of $NO$
• C. Increasing the concentration of the $C{l}_2$
• D. Doing all of these

Answer 1

The correct option is A Increasing the temperature

Rate constant is independent of the initial concentration of the reactants. It has a constant value at fixed temperature. According to Arrhenius equation, the value of rate constant can be increased by increasing the temperature
