According to the law of chemical equilibrium,

Options

A. the rate of forward reaction becomes equal to the rate of backward reaction when the chemical system attains equilibrium
B. a system can achieve the equilibrium state through forward as well as backward reaction
C. both (1) and (2)
D. the equilibrium constant `K_(eq)` is defined as the product of the equilibrium active masses of the products, each raised to the power that corresponds to its coefficient in the balanced equation, divided by the product of the equilibrium active masses of reactants, each raised to the power that corresponds to its coefficient in the balanced equation

Answer

D

Explanation

For
`ubrace(aA+bB)_("Reactants")hArr ubrace(cC+dD)_("Products")`
The law of chemical equilibrium says
`K_(eq)=([C]_(eq)^c[D]_(eq)^d)/([A]_(eq)^a[B]_(eq)^b)`
