QAIPMT-2006-Ch-2417: NEET 2006 Chemistry - Class 11 AIPMT-2006-Ch-2417 Solution: Assume each reaction is carried out in an open container. For…

Assume each reaction is carried out in an open container. For which reaction will ΔH=ΔE\Delta H=\Delta E?

Multiple Choice Options

  • A 2CO(g)+O2(g)→2CO2(g)2CO(g)+O_2(g)\rightarrow 2CO_2(g)
  • B H2(g)+Br2(g)→2HBr(g)H_2(g)+Br_2(g)\rightarrow 2HBr(g)
  • C C(s)+2H2O(g)→2H2(g)+CO2(g)C(s)+2H_2O(g)\rightarrow 2H_2(g)+CO_2(g)
  • D PCl5(g)→PCl3(g)+Cl2(g)PCl_5(g)\rightarrow PCl_3(g)+Cl_2(g)

Step-by-Step Verified Solution

We know that _ H = _ E + _ n g RT In the reaction, H 2 (g) + Br 2 (g) _ 2HBr(g) _ n g = 2 - (1 + 1) = 0 So, _ H = _ E for this reaction.
