The resction 2NO(g)+O2(g)2NO2(g) is second order in NO and first order in O2. When [NO}=0.4M and {O2]=2.5M, the observed rate of the ractign it a. oo00yrzo M/z. (a) What is the value of the rate constant? (b) What are the units of the rate constant? M1 M1s1 M0s1 M3s M1s2 M3s1 M2s1 The rate constant has no unit. M2s1 (c) What would happen to the rate if the concentration of NO were increased by a factor of 4 . 8 ? The rate of the reaction would increase The rate of the reaction would decresse By what factor would the rote of reaction increase? (d) What is the rate of reaction when [NO)=0.1M and O2]=0.74M] M/s
