The standard equilibrium constant K_P^ is positive and follows the relation K_P^ = e ^ - G^ / R T Choose the correct statement(s).

Options

1. Ad ( K_p^ ) d T = H^ R T^2 and the sign of H^ determines whether K_P^ increases or decreases as T increases.
2. BOnly the sign of S^ determines the temperature dependence of K_P^ .
3. CAt low T , equilibrium position is determined by internal energy change ( U^ ).
4. DAt high T , equilibrium position is determined by the entropy change ( . S^ ) .
