Below `1623 K, Al` can reduce `MgO` to `Mg`, but above `1623 K`, reverse is true.

CO is more effective reducing agent than coke below 983 K, but above 983 K the reverse is true. Why?

Carbon monoxide is more effective reducing agent than carbon below 983 K but above this temperature, the reverse is true. How would you explain this ?
