Multiple Choice

Kc and Kp are not ________.

Explanation:
For gases, the equilibrium constant can be expressed in terms of concentrations (Kc) or partial pressures (Kp). They’re connected by Kp = Kc (RT)^{Δn}, where Δn is the change in the number of moles of gas. This means they are not equal in general; they only become equal if there is no net change in gas moles (Δn = 0). Temperature also affects both constants, so equality is a special case rather than the rule.
