# Reaction rate

## Homework Statement

The reaction rate of nitrogen monoxide and oxygen into nitrogen dioxide is given by the expression
r = k [NO]2 [O2],
where r = reaction rate
k = reaction rate coefficient, which increases with increasing temperature.

## Homework Equations

What is the increase in the reaction rate when the concentration of nitrogen oxide is
doubled and the concentration of oxygen is tripled?

## The Attempt at a Solution

it's obvious that it increases 6 times.

No.

Start with a simpler problem - what happens to the reaction rate when the concentration of nitrogen oxide is doubled?

No.

Start with a simpler problem - what happens to the reaction rate when the concentration of nitrogen oxide is doubled?
ok it will be:
4*3 = 12
because: r = k [2*NO]2 * 3[O2]
