Chemical Kinetics - Result Question 9

####9. The rate of the reaction

2NO+Cl22NOCl is given by the rate equation rate =k[NO]2[Cl2]

[2010]

The value of the rate constant can be increased by:

(a) increasing the concentration of NO.

(b) increasing the temperature.

(c) increasing the concentration of the Cl2

(d) doing all of these

Show Answer

Solution:

  1. (b) 2NO(g)+Cl2 (g) 2NOCl(g)

Rate =k[NO]2[Cl2]

The value of rate constant can be increased by increasing the temperature and is independent of the initial concerntration of the reactants.
