Question

The reaction 2 NO(g) + O₂(g)--->2 NO₂(g) is second
order in NO and first order in O2. When 3NO₄ = 0.040 M,
and [O₂] = 0.035 M, the observed rate of disappearance
of NO is 9.3x 10-5 M/s. (a) What is the rate of disappearance
of O₂ at this moment? (b) What is the value of the
rate constant? (c) What are the units of the rate constant?
(d) What would happen to the rate if the concentration of
NO were increased by a factor of 1.8?
