Le Chateliers Principle 4

Question 1

K = product/reactant
How can a system be disturbed

Answer 1

Changing the reactant and product
Changing the pressure and volume
Changing the temperature
Adding inert gas
1. At constant volume
2. At constant temperature

Question 2

Kc=[pcl3] [cl2] / [pcl5] qc= [pcl3][cl2] / [2pcl5]
When the reactant concentration is double

Answer 2

Means Kc /2
Because rate is decreases the reaction move in forward directions

Question 3

Pcl5 —pcl3 + cl2
When cl2 is doubled

Answer 3

Reaction move in reverse direction

Question 4

Pressure change karne se

Answer 4

Kc ki value me kabhi bhi change nhi aata
Bsss uski position change hoti hai
Jab tk h”amara temperature Constant hai tb tk Koi Change nhi Atta

Question 5

Agr hum, volume decrease kare to pressure of system will increases

Answer 5

To decrease pressure reaction will shift toward the side where no of gaseous moles is less

Question 6

When we add inert gas at constant volume in an equilibrium

Answer 6

Then there will be no change in kp and kc value

Question 7

The addition of an inert gas at constant pressure

Answer 7

The equilibrium shift towards the greater no. Of moles
Mtlb ki inert gas Dayne se pressure decrease ho jata hai to ye shift ho jata hai towards more no. Of gaseous moles

Question 8

Write the formula of vant Hoff equation

Answer 8

Ln [ K2/ K1 ] = delta H/R [ T2 -T1 /T1xT2 ]
