Answer:
The correct answer is option A.
Explanation:
Equilibrium is a state when rate of forward reaction is equal to the rate of backward reaction. The concentration of reactants and products becomes constant at this state.
The ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients is termed as Equilibrium constant. It is denoted by [tex]K_{eq}[/tex].
aA + bB [tex]\rightleftharpoons [/tex] cC
[tex]K_{eq}=\frac{[C]^c}{[A]^a[B]^b}[/tex]
