    \(Q_c=\dfrac{[\mathrm{C}]^x[\mathrm{D}]^y}{[\mathrm{~A}]^m[\mathrm{~B}]^n} \quad\) for the reaction \(m \mathrm{~A}+n \mathrm{~B} \rightleftharpoons x \mathrm{C}+y \mathrm{D}\)
     
    \(Q_P=\dfrac{\left(P_C\right)^x\left(P_D\right)^y}{\left(P_A\right)^m\left(P_B\right)^n} \quad\) for the reaction \(m \mathrm{~A}+n \mathrm{~B} \rightleftharpoons x \mathrm{C}+y \mathrm{D}\)
