Current Question (ID: 18282)

Question:

$\text{The rate of the reaction}$ $2\text{NO} + \text{Cl}_2 \rightarrow 2\text{NOCl is given by the rate equation}$ $\text{rate} = k[\text{NO}]^2[\text{Cl}_2]$ $\text{The value of the rate constant can be increased by:}$

Options:

1. $\text{Increasing the concentration of NO}$
2. $\text{Increasing the concentration of Cl}_2$
3. $\text{Increasing the temperature}$
4. $\text{All of the above}$

Solution:

$\text{HINT: Rate constant is only temperature dependent.}$ $\text{Explanation:}$ $\text{The rate constant may also be expressed using the Arrhenius Equation:}$ $k = Ae^{-E_a/RT}$ $\text{It depends only on the temperature and not on the concentration of reactants and products.}$ $\text{By increasing temperature rate constant will also increase.}$
