Answer to Question #141791 in General Chemistry for mike

Question

The reaction, 2NO(g) + O2(g) → 2NO2(g) was found to be first order with respect to NO and second order with respect to O2.
a). Deduce the rate expression.

b). The starting reactant concentrations are 1.0mol dm-3. On the one set of axes sketch the expected shape of the concentration-time graph for this reaction with respect to:
(i). NO
(ii). O2
(iii). NO2

Answer 1

A) The rate law for 2NO(g) + O2(g) ====>2NO2(g) is rate=k[NO]^2[O2]. In addition to the mechanism, the following have been proposed: I. 2NO(g) +O2(g) ===> 2NO2(g) II.

B)
