The first law of thermodynamics, known as the law of conservation of energy, states that the total energy of an isolated system remains constant though it may change from one form to another. ∆G will be negative and reaction becomes spontaneous. Then the temperature above which the reaction will become spontaneous is …………. The values of H and S for a reaction are respectively 30 kJ mol -1 and loo kJ mol -1. In CaCO 3(S) → CaO (S) + CO 2(g) entropy change is positive in (a) and (b) entropy change is negative in (c) entropy change is zero. ∆S is expected to be maximum for the reaction
If the entropy change is 16 J mol -1 K -1. The molar heat of vaporization of a liquid is 4.8 kJ mol -1. During compression work is done on the system, hence w is positive. In an isothermal reversible compression of an ideal gas the sign of q, AS and w are respectivelyĭuring compression, the energy of the system increases, in isothermal condition, to maintain the temperature constant, heat is liberated from the system. The temperature of the system decreases in an ………… In a reversible process, the change in entropy of the universe is ‘ In an adiabatic process, which of the following is true? The amount of heat exchanged with the surrounding at constant temperature and pressure is called ………Īll the naturally occurring processes proceed spontaneously in a direction which leads to Choose the correct answer from the following: Tamilnadu Samacheer Kalvi 11th Chemistry Solutions Chapter 7 Thermodynamics Samacheer Kalvi 11th Chemistry Thermodynamics Textual Evaluation Solved
