Rate = 430 M^-2 s^-1 [NO_2]^2 [O_3] Give the direction of the reaction, if K >>1: a. The forward reaction favored. b. The reverse reaction is favored. c. If the temperature is raised, then the forward reaction is favored. d. If the temperature is raised, then the reverse reaction is favored.Explanation / Answer
(1)
The weak attractive force between nucleus of one atom and electrons of other is termed the London force.
(2)
For a first order reaction, the reaction rate is directly proportional to the reactant concentration.
(3)
Foam is an example of a gas dispersed in a liquid phase.
(4)
From the data table we see that doubling O3 keeping other constant doubles the reaction rate, and doubling NO2 keeping the O3 constant also doubles the rate. SO reaction is first order with respect to both of them.
So correct option is (c)
(5)
The forward reaction is favored if the value of equlibrium constant K is greater than 1.
