QuestionWhat happens to the equilibrium when HI\mathrm{HI} gas is added to the system: A, B, C, or D? 51.8 kJ+H2( g)+I2( g)2HI(g)51.8 \mathrm{~kJ}+\mathrm{H}_{2}(\mathrm{~g})+\mathrm{I}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g})

STEP 1

Assumptions1. The system is initially at equilibrium. . The system obeys Le Chatelier's principle, which states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
3. HI\mathrm{HI} gas is added to the system.

STEP 2

According to Le Chatelier's principle, if a system at equilibrium is disturbed, the system will adjust itself to reduce the disturbance. In this case, the disturbance is the addition of HI\mathrm{HI} gas.

STEP 3

Since HI\mathrm{HI} gas is added to the system, the system will try to reduce the concentration of HI\mathrm{HI} gas to reestablish equilibrium.

STEP 4

The reaction can reduce the concentration of HI\mathrm{HI} gas by shifting to the left (reactants). This will consume HI\mathrm{HI} gas and produce H2\mathrm{H}_{2} and 2\mathrm{}_{2}.

STEP 5

Therefore, the reaction shifts to the left (reactants) and the concentrations of H2\mathrm{H}_{2} and 2\mathrm{}_{2} increase.So, the correct answer is D. The reaction shifts to the left (reactants) and the concentrations of H2\mathrm{H}_{2} and 2\mathrm{}_{2} increase.
