The reaction NO(g)+1/2Br2(g)??>NOBr(g) is second order in nitrogen oxide and first order in bromine. The rate of the reaction is 1.6x10?8 mol/L-min when the nitrogen oxide concentration is 0.020 M and the bromine concentration is 0.030 M. c. at what concentration of nitrogen oxide is the rate 2.0x10^-6 mol/L-min and the bromine concentration one fourth of the nitrogen oxide concentration?
