Which among the following is incorrect about equilibrium state?

    If a system is at equilibrium, the relation between rate of forward to the rate of reverse reaction is

The enthalpy and entropy change for the reaction are $30 \mathrm{kJ} {\mathrm{mol}}^{-1}$ and $105 \mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}$, respectively. The temperature at which the reaction will be in equilibrium is

${\mathrm{Br}}_2 \left(\mathrm{l}\right)+{\mathrm{Cl}}_2 \left(\mathrm{g}\right)⟶2\mathrm{BrCl} \left(\mathrm{g}\right)$

Nitric oxide reacts with ${\mathrm{Br}}_2$ and gives nitrosyl bromide as per the reaction given below.

                      $2\mathrm{NO}\left(\mathrm{g}\right) + {\mathrm{Br}}_2\left(\mathrm{g}\right) \rightleftharpoons 2\mathrm{NOBr}\left(\mathrm{g}\right)$

When $0.087$ mole of $\mathrm{NO}$ and $0.0437$ mole of ${\mathrm{Br}}_2$ are mixed in a closed container at a constant temperature, $0.0518$ mole of $\mathrm{NOBr}$ is obtained at equilibrium. Calculate the equilibrium amount of $\mathrm{NO}$ and ${\mathrm{Br}}_2$.
