The reaction equation, given previously as: r = k 1 s t − k 2 u v {\displaystyle r=k_{1}^{s}^{t}-k_{2}^{u}^{v}} − d d t = k f t − k b t {\displaystyle -{\frac {d}{dt}}=k_{f}_{t}-k_{b}_{t}} The derivative is negative because this is the rate of the reaction going from A to B, and therefore the concentration of A is decreasing.
Persamaan reaksinya, diberikan sebelumnya sebagai: r = k 1 s t − k 2 u v {\displaystyle r={k_{1}^{s}^{t}}-{k_{2}^{u}^{v}}\,} − d d t = k f t − k b t {\displaystyle -{\frac {d}{dt}}={k_{f}_{t}}-{k_{b}_{t}}\,} Turunan tersebut bernilai negatif karena merupakan laju reaksi yang berjalan dari A menuju B, dan karenanya konsentrasi A berkurang.
