Which of the following is not a characteristic property of chemical equilibrium?
1 Rate of forward reaction is equal to rate of backward reaction at equilibrium
2 After reaching the chemical equilibrium, the concentrations of reactants and products remain unchanged with time
3 $\operatorname{For} \mathrm{A}(\mathrm{g}) \rightleftharpoons \mathrm{B}(\mathrm{g}), \mathrm{K}_{\mathrm{c}}$ is $10^{-2}$, If this reaction is carried out in the presence of catalyst, that value of $\mathrm{K}_{\mathrm{c}}$ decreases
4 After reaching the equilibrium, both forward and backward reactions continue to take place
Explanation:
For $\mathrm{A}(\mathrm{g}) \rightleftharpoons \mathrm{B}(\mathrm{g}), \mathrm{K}_{\mathrm{c}}=10^{-2}$ If this reaction is carried out in the presence of catalyst, the value of $\mathrm{K}_{\mathrm{C}}$ (equilibrium constant) not effect.

The rate, at which a substance reacts, depends upon its
1 equivalent mass
2 molecular mass
3 active mass
4 atomic mass
Explanation:
The rate at which a substance reacts depends upon its active mass as the rate of reaction is directly proportional to concentration of each reactant and product.

According to Ellingham diagram, the oxidation reaction of carbon to carbon monoxide may be used to reduce which one of the following oxides at the lowest temperature?
1 $\mathrm{Al}_{2} \mathrm{O}_{3}$
2 $\mathrm{Cu}_{2} \mathrm{O}$
3 $\mathrm{MgO}$
4 $\mathrm{ZnO}$
5 $\mathrm{FeO}$
Explanation:
$\mathrm{Cu}_{2} \mathrm{O}$ is least stable among all so the oxidation reaction of carbon to carbon monoxide may be used to reduce this at the lowest temperature.
