  • Which statement characterize a chemical system at equilibrium ? (P)the rate of the forward reaction is equal to the rate of the reverse reaction (Q)The concentrations of the reactants and products are equal.

    A
    P only
    B
    Q only

  • Mass action ratio or reaction quotient Q for a reaction can be calculated using the law of mass actionl, A(g)+B(g)hArrC(g)+D(g) Q=([C][D])/([A][B]) The value of Q decides whether the reaction is at equilibrium or not. At equilibrium, Q=K For non-equilibrium process QneK When QgtK , reaction will be favoured in backward direction and when QltK , it will be favoured in forward direction. In the following reaction : 2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g) The equilibrium is not attained. The rate of forward reaction is greater than that of backward reaction. Thus, which of the following is the correct relation between K_(p) and Q_(p) ?

    A
    `K_(p)=Q_(p)`
    B
    `Q_(p)ltK_(p)`
    C
    `Q_(p)ltK_(p)`
    D
    `K_(p)=Q_(p)=1`
