For the Reaction CuS(s) + H₂(g) $\leftrightharpoons$ H₂S(g) + Cu(s) $\Delta$ G ^$\circ$

question 82

True/False

For the reaction CuS(s) + H₂(g) $\leftrightharpoons$ H₂S(g) + Cu(s),
$\Delta$ G ^$\circ$ _f (CuS) = -53.6 kJ/mol
$\Delta$ G ^$\circ$ _f (H₂S) = -33.6 kJ/mol
$\Delta$ H ^$\circ$ _f (CuS) = -53.1 kJ/mol
$\Delta$ H ^$\circ$ _f (H₂S) = - 20.6 kJ/mol
This reaction proceeds spontaneously at 298 K and 1 atm pressure.
