Temperature dependence of reaction rates
Well mostly it does but there can be exceptions.

Eg Consider the reaction $$\ce{2NO + O_2 -&gt; 2NO_2}$$

It has a negative temperature dependence. The rate decrease in increasing the temperature.

There is a simple reason to why this happens.
We have a RDS with an intermediate species. The rate determining step must have a positive temperature dependence.  But the preceding equilibrium that produces the intermediate species could have a negative temperature dependence , that affects the overall reaction.

The Mechanism

$\ce{NO + O2 &lt;=&gt; ONOO}$ Fast but reversible

$\ce{ONOO + NO -&gt; 2NO2}$ Rate determining step

If Step 1 is exothermic, as a bond is being formed between the reactants. 
This has a greater impact on the overall reaction and by le Chatlier's principle the equilibrium shift backward . We get a negative temperature dependence!
