Answer 1

Answer #1

Ans.

Reaction :

2HBr(g) + 72.7 KJ <----> H2(g) + Br2(g)

As heat is added in the reaction , so , this reaction is endothermic reaction

According to Le Chatelier's principle , in an endothermic reaction , when temperature is increased , the equilibrium will shift to the right side

Therefore , answer is (B) , right , and the concentration of HBr(g) will decrease
