  • question_answer
    For a chemical reaction at equilibrium the value of degree of dissociation is given by\[\alpha =\frac{{{M}_{t}}-{{M}_{0}}}{{{M}_{0}}(n-1)}\]. For this equation to be applicable pick out the incorrect statement.

    A) The volume of the system must be constant

    B) The reacting system must be gaseous

    C) Temperature and pressure must be constant

    D) Only one mole of the reactant must be present

    Correct Answer: A

    Solution :

    [a] For the equation to be applicable, systems should be gaseous, only one reactant and it son mole should be taken. It is carried out as at constant temperature and pressure. So, volume does not remain constant.
