Therefore, K = × γ ( A B ) γ ( A ) γ ( B ) {\displaystyle K={\frac {}{}}\times {\frac {\gamma (AB)}{\gamma (A)\gamma (B)}}} When each activity coefficient has the dimension 1/concentration, K remains dimensionless.
Maka, K = × γ ( A B ) γ ( A ) γ ( B ) {\displaystyle K={\frac {}{}}\times {\frac {\gamma (AB)}{\gamma (A)\gamma (B)}}} Di mana setiap koefisien aktivitas memiliki dimensi 1/konsentrasi, K tetap tak berdimensi.
