For the following equation, 2HBr(g) \(\rightleftharpoons\) H2(g) + Br2(g); are both KP and KC are equal?(a) yes(b) cannot say(c) no(d) depends on the temperatureThe question was asked by my school teacher while I was bunking the class.I would like to ask this question from Homogeneous Equilibria topic in division Equilibrium of Chemistry – Class 11 |

Answer» CORRECT option is (a) yes For explanation: We have here KC = [H2][BR2]/[HBR]^2; KP = [pH2][pBr2]/[PHBR]^2, where pH2 = [H2]RT, pBr2 = [Br2]RT and [pHBr] = [HBr]RT. So in this case as Δng = 0, where Δng = moles of products – moles of reactants which are in gaseous state only, both KP and KC are equal. |
