Generally, reaction rates increase when the temperature is increased.

Question 1 options:

Save

Question 2 (0.5 points)

What will happen to the position of equilibrium if the volume of the system is decreased in the reaction shown?

Question 2 options:

It will shift to the left

It will shift so that the system volume is increased again

It will shift to the right

The position will shift left and then return to its original place

There will be no shift in the position of equilibrium

Question 4 (0.5 points)

Choose the correct equilibrium constant expression for the equilibrium

Question 4 options:

1) True 2) False

This is true statement

K = A*e^(-Ea/RT)

So, increasing T will increase the rate

Answer: true

We are decreasing volume here

In other words we are trying to increase pressure

so, according to Le Chatelier's principle,

Reaction will try to decrease the pressure

Hence it will move in a direction which have lesser gaseous molecules

Here product has less gaseous molecule

So equilibrium will move to right

Answer: It will shift to the right
