Rate constant units

Postby 405161024 » Wed Mar 13, 2019 8:32 pm

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