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.
