Match the column:
Column-I | Column-II |
(i) Endothermic reactions | [A] H2(g)+ O2(g)→H2O(l) |
(ii) Exothermic reaction | [Β] NH3(g) → N(g) + 3H(g) |
(iii) |ΔH| = |ΔE| | [C] CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) |
(iv) |ΔH| ≠ |ΔE| | [D] H2(g) +Cl2(g) → HCl (g) |
Text Solution
Verified by Experts(i) [B]; (ii) [A]; (iii) [D]; (iv) [A]
(i) [B]
(ii) [A], [C], [D]
(iii) [D]
(iv) [A], [B], [C]
Sol. (i) NH 3 (g) → N(g) + 3H(g)
(ii) H 2 (g)+ 
O 2 (g) → H 2 O( l ), CH 4 (g) + 2O 2 (g) → O 2 (g) 2H 2 O( l ), 
H 2 (g) + 
Cl 2 (g) → HCl (g)
(iii) 
H 2 (g) + 
Cl 2 (g) → HCl (g)
(iv) H 2 (g)+ 
O 2 (g) → H 2 O( l ), NH 3 (g) → N(g) + 3H(g), CH 4 (g) + 2O 2 (g) → O 2 (g) 2H 2 O( l )
