EMRS PGT Chemistry Mock Test - 7 - Question 17

When hydrochloric acid is added to cobalt (II) nitrate solution at room temperature, the following reaction takes place

Q. The solution is blue at room temperature. However, it turns pink when cooled in a freezing mixture. Based upon this information, which of the following expression is correct for the forward reaction?

Detailed Solution for EMRS PGT Chemistry Mock Test - 7 - Question 17


According to the given information, the solution turns pink when cooled in freezing mixture. So, the equilibrium has shifted in backward direction. So we can say that the reaction is endothermic and ∆H for the reaction is greater than zero. This is because, endothermic reactions have ∆H > 0 and they proceed in reverse direction.

EMRS PGT Chemistry Mock Test - 7 - Question 21

Direction (Q. Nos. 1-13) This section contains 13 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONLY ONE option is correct.

Q. If the enthalpy of HCI (g) and Cl- (aq) are - 92.30 kJ mol-1 and - 167.44 kJ mol-1 respectively, then ΔrH° for the following reaction is

HCI (g) + aq → H(aq) + Cl(aq)

Detailed Solution for EMRS PGT Chemistry Mock Test - 7 - Question 21

Enthalpy of reaction = ∑enthalpy of products - ∑enthalpy of reactants
Therefore
∆Hreaction = -167.44 - (- 92.30) (∆Hformation of H+ is 0)
= -75.14 kilo J / mole
