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

$K_p$ will not be affected by the change in the total pressure or amounts of hydrogen and iodine, present or the catalyst.
Equilibrium constants only changes with change in temperature. So, only temperature affects $K_p$.
