For the Reaction CuS(s)+ H₂(g)
H₂S(g)+ Cu(s) $\Delta$

question 16

Short Answer

For the reaction CuS(s)+ H₂(g)
H₂S(g)+ Cu(s),
$\Delta$ G°_f (CuS)= -53.6 kJ/mol
$\Delta$ G°_f (H₂S)= -33.6 kJ/mol
$\Delta$ H°_f (CuS)= -53.1 kJ/mol
$\Delta$ H°_f (H₂S)= - 20.6 kJ/mol
Will this reaction proceed spontaneously at 298 K and 1 atm pressure?
