## Order reactions and rate

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

### Order reactions and rate

How can I tell the difference between order reactions? What is the difference between order reactions and rate reactions?

The rate law shows the order of each reactant. The order of an individual reactant is the power it's raised to (zero if it's not in the rate law at all), the overall reaction order is the sum of all individual reactant orders.

The overall reaction order is N + M in the equation Lavelle showed in class where the reactants are raised to N or raised to M. N and M represent the order of that specific reactant
