Practice ProblemATTEMPT

$\Delta G°$ for the reaction:

${\text{H}}_{\text{2}}(g)+{\text{ I}}_{\text{2}}\text{(}s\text{) }\rightleftarrows \text{ 2HI(}g\text{)}$

is $\text{2}\text{.60 kJ/mol}$ at $\text{25}°\text{C}\text{.}$ Calculate $\Delta G$, and predict the direction in which the reaction is spontaneous if the starting concentrations are $P_{\text{H2}}\text{= 5}\text{.25 atm and }{P}_{\text{HI}}\text{= 1}\text{.75atm}\text{.}$
