2.
If [A] is the concentration of A at any time t and [Ao] is the concentration at t = 0, then for the first order reaction, the rate equation can be written as ______.
\(k=\frac { 2.303 }{ t } \log { \left[ \frac { A }{ { A }_{ 0 } } \right] } \)
\({ k }_{ t }=2.303\log { \left[ \frac { { A }_{ 0 } }{ \left[ A \right] } \right] } \)
\(k=2.303\log { \left[ \frac { { A }_{ 0 } }{ \left[ { A }_{ 0 } \right] -\left[ A \right] } \right] } \)
\(k=\frac { 2.303 }{ t } \log { \left[ \frac { { A }_{ 0 } }{ { A } } \right] } \)
