Question

what would be the effect on the reaction rate if the O2 were doubled?

Answer 1

What chemical reaction are you discussing?

Answer 2

@AcademicGurusInc 2NO(G) + O2 (G) 2 NO2 (G)

Answer 3

I've already written the equilibrium constant expression for the reaction*

Answer 4

http://www.chemguide.co.uk/physical/basicrates/concentration.html

So here you are increasing the concentration of one of the reactants - oxygen in this case. The website I attached discusses different scenarios that affect the reaction rate - concentration, temperature, catalysts ...

What did you find?

Answer 5

Thank you. And I found/got this: Kc = [NO2]2/[No]2[O2]= 4.67 x 1013

Answer 6

You wrote the equilibrium constant correctly.

Answer 7

Great! Thank you
