When a question asks us to identify the equilibrium expression for K, can we use either Kp (use partial pressures for the expression) or Kc (use concentrations for the expression)? or do we have to use a specific one in certain situations?

When calculating Kc, I believe you can use the [P]/[R] equation. You can also use PV=nRT when converting between Kc and Kp.
It depends on the state of the materials given. If the chemical equation involves gases, usually partial pressures. If the chemical equation involves AQ state chemicals, then usually use concentrations.
