Question

For the reaction: $H_2\left(g\right)+I_2\left(g\right)\rightleftharpoons 2HI\left(g\right)$ the equilibrium constant $K_p$ changes with

• A. total pressure
• B. catalyst
• C. the amounts of $H_2$ and $I_2$ present
• D. temperature

Answer 1

The correct option is D temperature

For the reaction, $H_2\left(g\right)+I_2\left(g\right)\rightleftharpoons 2HI\left(g\right),$ the number of moles of gaseous products is equal to gaseous reactants. Thus, the equilibrium constnat $K_p$ is independent of
(A) Total pressure
(B) Catalyst
(C) The amounts of $H_2$ and $I_2$ present.
However, it changes with Temperature.
