Question

For the reaction $H _{2}( g )^{+} I _{2}( g ) \longrightarrow 2 HI ( g )$, the equilibrium constant $Kp$ changes with

• A. total pressure
• B. catalyst
• C. the amount $H_2$ and $I_2$
• D. temperature

Answer 1

Answer: (D)

For the reaction, $H _{2}( g )+ I _{2}( g ) \rightleftharpoons 2 HI ( g )$, the number of moles of gaseous reactants is equal to the number of moles of gaseous products. The equilibrium constant $K _{ p }$ is independent of (A) Total pressure
(B) Catalyst
(C) The amounts of $H _{2}$ and $I _{2}$ present
However, it changes with Temperature
