## Rate constant units

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Rate constant units

could someone explain to me how to find the units for the rate constant? Is the unit of the rate always moles per second?

Rate is moles per liter per second

The units for rate are mol.L-1.s-1, change of concentration over change in time. The rate constant units depend on the order of the reaction. To put it simply, a 0th order k: mol.L-1.s-1, 1st order k: s-1, 2nd order k: mol-1.L.s-1

Can you have it be moles per mL per second? Or per day?
