Question

What are the factors affecting chemical equilibrium?

Answer 1

See below.

Explanation:

Equilibrium is affected by :
`1)` Pressure
`2)` Temperature
`3)` Concerntration

Remember: CATALYST DOES NOT AFFECT THE EQUILIBRIUM IT JUST INCREASES THE RATE .

PRESSURE:
To increase the yeild , INCREASE the pressure ONLY if the LEFT side of the reaction has MORE NO.OF MOLECULES .
e.g: `N_2` `+` `3``H_2` `rightleftharpoons` `2` `NH_3`

So, left side has `4` molecules and right has `2` therefore you should increase pressure for increasing yeild.

TEMPERATURE:
To increase yeild , INCREASE the TEMPERATURE ONLY if the FORWARD reaction is ENDOTHERMIC .

CONCERNTRATION:

You can increase the yeild by removing the product formed.
