45. Ne + 3/He)2NIIE: If some HCI gas is passed into the reaction mixture at the equilibrium of this reaction 1) Equilibrium shifts towards left 2) Equilibrium shifts towards right 3) Concentration of H, increases 4) The equilibrium is not affected 46. When a bottle of cold drink is opened, the gas comes out with fizzes due to 1) Decreases in temperature 2) Increase in pressure 3) Decrease in pressure suddenly which results in decrease of solubility of CO, gas in water 4) None of the above 47. In the equilibrium NH HS(s) NH,(g)+H S(g) the forward reaction can be favoured by 1) Adding some more NH HS 2) Adding some more NH, 3) Removing some NH, from the reaction mixture 4) Adding some more H,S 48. At constant pressure, the presence of inert gases 1) Reduces the dissociation of PCI, 2) Increase the dissociation of PCI, 3) Does not affect the degree of dissociation of PCI, 4) Steps up the formation of PCI, 49. In a reaction A,(g) + 4B,(g) + 2AB,(g); AH
