## Example?

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

### Example?

What’s a real life example of a second order reaction?

### Re: Example?

An example of a second order reaction is the formation of oxygen molecules from the combustion of oxygen atoms and ozone (O + O3 → O2 + O2).

Another example is the reaction of nitrogen dioxide with fluorine gas.

NO2 (g) + F2 (g) → 2NO2F(g)

The respective rate would be rate = k[NO2][F2]. Since both NO2 and F2 are of the first order, the overall order is 1 + 1 = 2.

another example is the decomposition of nitrogen dioxide

2NO2(g)-->2NO(g)+O2(g)

r= k[NO2]^2

### Re: Example?

This is an intermediate reaction of another reaction, but it is still second order:
O + H2O → 2 OH
A common product of combustion is water, and reacts with all the loose oxygen atoms produced in other reactions to form hydroxides.
