Question Description
The contributions of both heat (enthalpy) and randomness (entropy) shall be considered to the overall spontaneity of a process. When deciding about the spontaneity of a chemical reaction or other process, we define a quantity called the Gibbs energy change (G).G = H TSwhere,H = Enthalpy change ; S = Entropy change;T = Temperature in kelvin.If G 0, Process is spontaneous ; G = 0, Process is at equilibrium, AG 0, Process is non-spontaneous.Q.Quick lime, Ca0 is produced by heating limestone, CaC03 to drive off C02 gas.CaC03 (s) CaO (s) + C02 (g), (H) = 180 KJ, S = 150 J/K.Assuming that variation of enthalpy change and entropy change with temperature to be negligible, choose the correct option :a)Decomposition of CaCO3 (s) is never spontaneous.b)Decomposition of CaCO3 (s)becomes spontaneous when temperature is less than 900C.c)Decomposition of CaC03 (s) becomes non-spontaneous when temperature is greater than 1000Cd)Decomposition of CaCO3(s) becomes spontaneous whentemperature is greater than 927C.Correct answer is option 'D'.
