Easy MCQ +4 / -1 PYQ · JEE Mains 2022

Match List-I with List-II.

List - I List - II
(A) Spontaneous process (I) $\Delta H < 0$
(B) Process with $\Delta P = 0$, $\Delta T = 0$ (II) $\Delta {G_{T,P}} < 0$
(C) $\Delta {H_{reaction}}$ (III) Isothermal and isobaric process
(D) Exothermic Process (IV) [Bond energies of molecules in reactants] $-$ [Bond energies of product molecules

Choose the correct answer from the options given below :

  1. A (A) - (III), (B) - (II), (C) - (IV), (D) - (I)
  2. B (A) - (II), (B) - (III), (C) - (IV), (D) - (I) Correct answer
  3. C (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
  4. D (A) - (II), (B) - (I), (C) - (III), (D) - (IV)

Solution

(A) For a spontaneous process $\Delta$G<sub>T,P</sub> < 0 <br/><br/> (B) $\Delta$P = 0 $\to$ Isobaric process, $\Delta$T = 0 $\to$ Isothermal process<br/><br/> (C) $\Delta$H<sub>reaction</sub> = ($\Sigma$ Bond energies of reactants) - ($\Sigma$ bond energies of products) <br/><br/> (D) $\Delta$H < 0 is for exothermic reaction
