## rate

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

### rate

What is the relationship between the second order and it's rate?

### Re: rate

The integrated rate law for a second-order reaction is
kt + 1/[A]o = 1/[A}

The graph has a positive k, straight line slope which means that over time concentration of A is increasing

For the general rate law, the units for K would be 1/(M * s)

### Re: rate

Second order reactions have a graph of 1/(A) v time. If the reaction is second order, the graph would appear linear with k being +slope of the line.

### Re: rate

if we change a second order equations reactant by a factor, its rate will change by the factor^2
