  • Entropy is measure of degree of randomness. Entropy is directly proportional to temperature. Every system tries to acquire maximum state of randomness or disorder. Entropy is measure of unavailable energy. Unavailable energy = Entropy x Temperature. The ratio of entropy of vaporization and boiling point of substance remains almost constant. Which of the following has DeltaS = +ve ?

    A
    `H_(2)(g) + Cl_(2)(g) to 2HCl(g)`
    B
    Boiling of egg
    C
    Crystallization of sugar
    D
    Formation of complex compound
