ASSERTION For the physical equilibrium H2O(s) ⇌ H2O(l) on increasing temperature and increasing pressure more water will form. REASON Since the forward reaction is endothermic in nature and volume of water is greater than that of the volume of ice. The most stable oxides of nitrogen will be : November 11, 2020 Category: Chapter 5 [...]

Statement 1 : For a reaction at certain temperature A(g) + B(g) ⇌ C(g) there will be no effect by a additional of inert gas at constant volume. Statement 2 : Molar concentration of all gases remains constant. The most stable oxides of nitrogen will be : November 11, 2020 Category: Chapter 5 - Chemical [...]

Statement 1 : The equilibrium constant for an exothermic reaction at high temperature decreases. Statement 2 : Since in K2/K1 = Triangle H degree/R (1/T1 – 1/T2 ) and for exothermic reaction, triangle H degree = -ve and thereby, K2/K1 < 1 K2/K1 < 1 Statement 1 : The equilibrium constant for an exothermic reaction [...]
