Consider the reaction below at 298K, C("graphite")+2H_(2)(g) to CH_(4) (G) triangle_(f) H^(@) ("Kj/mol") -74.9 S_(m)^(@) ("J/mol-K")+5.6 +130.7 +186.3 Which statement below is correct?

Answer»

`triangle_(r)G^(@)` is -50.8 KJ and the REACTION is DRIVEN by ENTHALPY only
`triangle_(r)G^(@)` is -50.8 kJ and the reaction is driven by entropy only
`triangle_(r)G^(@)` is +50.8 kJ and the reaction is driven by both enthalpy and entropy
`triangle_(r)G^(@)`is -50,8 kJ and the reaction is driven by both enthalpy and entropy
