Predict whether it is possible or not to reduce magnesium oxide using carbon at `298K` according to the reaction.  `MgO(s) +C(s) rarr Mg(s) +CO(g)`  `Delta_(r)H^(Theta) = +491.18 kJ mol^(-1)` and `Delta_(r)S^(Theta) = 197.67 J K^(-1) mol^(-1)`  If not at what temperature, the reaction becomes spontaneous.
