Chemical Equilibrium

Energy has different forms which include

Write an example for homogeneous equilibrium reaction.

Which type of chemical reaction attains equilibrium?

Statement - $1$: A catalyst increases the equilibrium constant at any fixed temperature. Statement - $2$: By the uses of catalyst the rate of the reaction increases.

The equilibrium constant for the reaction:

${\mathrm{N}}_{2\left(\mathrm{g}\right)}\mathrm{ }+\mathrm{ }{\mathrm{O}}_{2\left(\mathrm{g}\right)}\mathrm{ }\rightleftharpoons \mathrm{ }2\mathrm{N}{\mathrm{O}}_{\left(\mathrm{g}\right)}\mathrm{ }\mathrm{i}\mathrm{s}\mathrm{ }4\mathrm{ }\times \mathrm{ }{10}^{–4}\mathrm{ }\mathrm{a}\mathrm{t}\mathrm{ }200\mathrm{ }\mathrm{K}.$ In the presence of a catalyst, equilibrium is attained $10$ times faster. Therefore, the equilibrium constant in the presence of a catalyst at $200 \mathrm{K}$ is:

The equilibrium constant for the reaction :
${\text{N}}_2\left(\text{g}\right)+{\text{O}}_2\left(\text{g}\right)\rightleftharpoons 2\text{NO}\left(\text{g}\right)$ is is 4 × 10^–4 at 2000 K
In the presence of a catalyst, the equilibrium is attained ten times faster. Therefore, the equilibrium constant, in presence of the catalyst, at 2000 K is

For a reaction at equilibrium, which of the following statements is correct?

What will be the effect of addition of a catalyst at constant temperature?
