Application +4 | -1

For a reaction

{H_2}(g) + {I_2}(g) \to 2HI(g),

\Delta \,H = 37.5\,\,KJ/mol

and

\Delta S = 150\,\,J{K^{ - 1}}\,\,mo{l^{ - 1}}

the temperature at which the reaction will be at equilibrium is

View answer and explanation

Correct option: B

250\,\,\mathrm{K}

Option B (

250\,\,\mathrm{K}

) is correct because at equilibrium,

\Delta G = 0

, and we can solve for the temperature using the given

\Delta H

and

\Delta S

values.
