Type of reaction N 2 O 4 heat heat cool 2NO 2 .​

Answer 1

Answer:

Ramesh's total annual income in the financial year 2008-2009 was 23,00,000. He deposited 1000 every month in general provident fundland paid an annual premium o 12.000 on life insurance policy. If there is no tax on income up to 1,50,000 and 10 tax on income above 1,50,000 and maximum savings permissible under all schemes are 1,00,000 then calculate the tax payable by him at the end of the year where the educational sub-tax is 3% of income tax.

Answer 2

Explanation:

Reaction at equilibrium

N

2

O

4

⇌2NO

2

(1) According to Le chatelier's principle: Increasing the pressure on a gas reaction shifts the position of equilibrium towards the side with fewer molecules.

So, it will move in backward direction which leads to formation of N

2

O

4

from NO

2

.

(2) Addition of an inert gas at constant pressure will increase volume and equilibrium shifts towards more number of molecules i.e. there will be decomposition.

(3) Decomposition of N

2

O

is endothermic. So, the reaction will move in forward reaction when the temperature is increased.
