Question

The following diagrams represent mixtures of NO(g) and O2(g). These two substances react as follows: 2NO(g)+O2(g)→2NO2(g) It has been determined experimentally that the rate is second order in NO and first order in

Answer 1

The right answer is the mixture 1. which ks fast

Step-by-step explanation:

Factors affecting rates of reactions

a) Nature of reactants

2NO(g) + O

2(g) -> 2NO

2(g) fast

2CO(g) + O

2(g) -> 2CO

2(g) slow

b) Concentration of reactants: reactions proceed by

collisions between reactants

c) Temperature: In general, as T increases, rate increases

d) Catalyst: increases rate of reaction

e) Surface

f) Nature of solvent
