# rates of reaction question? watch

1. THE QUESTION:

what would happen to the rate of reaction if the concentration of NO is halved?

It's 0.25%
How do you get that??

*Really easy question, but my brain has complicated things, and now I'm confused af

Edit: would it be doing (H2 × 1) × (NO × 1/2)^2 ???

Because the reaction is order 2 with respect to the NO, as seen by the fact that the NO is sqared in the rate equation. Thus is you double its concentration the rate will quadruple, and if you half its concentration the rate will decrease by a factor of 4.
