At Equilibrium

Chemistry Level 1

What is the effect of halving \text{halving} the p r e s s u r e \color{#3D99F6}{pressure} by doubling \text{doubling} the v o l u m e \color{#20A900}{volume} on the following system,

H 2 ( g ) + I 2 ( g ) 2 H I ( g ) \large H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}

Details: \text{ Details: }

  • System is in equilibrium \text{equilibrium} at 500℃.

  • X ( g ) X_{(g)} means substance X is in gaseous phase \text{gaseous phase} .

Changing the pressure of an equilibrium mixture affects the position of equilibrium only when there are an unequal number of moles of gaseous products and reactants. In this case, there are the same number of moles of gaseous products and reactants, 2. Hence, no effect is observed.
