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.

ok it will be:
4*3 = 12
because: r = k [2*NO]2 * 3[O2]

This is a correct answer, but not to the question I asked.

You are so chaotic it is impossible to help.
