Interpretation:
In the formation of carbonylbromide from Carbon monoxide and Bromine, the partial pressure of Bromine is decreased into 0.50, now the partial pressure of all gases has to be calculated after equilibrium is re-established.
Concept Introduction:
Le Chatelier's principle:
It states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
