K = { A B } { A } { B } {\displaystyle K={\frac {\{AB\}}{\{A\}\{B\}}}} Now, each activity term can be expressed as a product of a concentration {\displaystyle } and a corresponding activity coefficient, γ ( X ) {\displaystyle \gamma (X)} .
K = { A B } { A } { B } {\displaystyle K={\frac {\{AB\}}{\{A\}\{B\}}}} Sekarang, setiap istilah aktivitas dapat dinyatakan sebagai perkalian konsentrasi {\displaystyle } dan koefisien aktivitasnya, γ ( X ) {\displaystyle \gamma (X)} .
