Consider the following reaction, which is carried out at 300 K:

CH3CH2OH + 3O2 → 2CO2 + 3H2O ∆H = –1,235 kJ/mol and ∆S = +0.22kJ/mol•K

1.) What is the value of ∆G? Show your work.
2.)Classify the reaction as spontaneous or nonspontaneous.
3.)Suggest why the value for ∆S is positive in this reaction

Respuesta :

G = H - T S 

-1235 - (300 x 220) 

-67.24kJ/mol

Since the Gibbs energy reaction is negative the reaction is spontaneous
