Question

choose the correct definitions for k, k_p, and q
(select all that apply.)
q is equilibrium constant as determined by the law of mass action. for q, concentration units of mol/l are used.
q is called the reaction quotient. q has the exact same form as k or k_p, but instead of equilibrium concentrations, initial concentrations are used to calculate the q value.
k_p is equilibrium constant as determined by the law of mass action. for k_p, partial pressures in units of atm are used (generally).
k_p is equilibrium constant as determined by the law of mass action. for k_p, concentration units of mol/l are used.

Explanation:

• For \(Q\) (Reaction Quotient):
• \(Q\) has the same form as \(K\) or \(K_p\). But instead of equilibrium concentrations (for \(K\)) or equilibrium partial - pressures (for \(K_p\)), initial concentrations (when using \(Q\) with concentration - based expressions) or initial partial - pressures (when using \(Q\) with pressure - based expressions) are used.
• For \(K_p\):
• \(K_p\) is the equilibrium constant determined by the law of mass action. For \(K_p\), partial pressures (in units of atm, generally) are used.
• For \(K\):
• \(K\) is the equilibrium constant determined by the law of mass action. For \(K\), concentration units of mol/L are used.

Answer:

• \(Q\) is called the reaction quotient. \(Q\) has the exact same form as \(K\) or \(K_p\), but instead of equilibrium concentrations, initial concentrations are used to calculate the \(Q\) value.
• \(K_p\) is equilibrium constant as determined by the law of mass action. For \(K_p\), partial pressures in units of atm are used (generally).
• \(K\) is equilibrium constant as determined by the law of mass action. For \(K\), concentration units of mol/L are used.
