PCL5(g)= PCL3(g) + Cl2(g)

In the reaction above, a decrease in pressure will
A
Decelerate the reaction
B
Increase yield of Pcl3
C
Increase the yield of Pcl5
D
Accurate the reaction
correct option: b
If we decrease the pressure in the reaction, there will be rapid breakage spilling of pcl5. And these follows a principle that molecule of gases tends to move from a region of higher pressure to low pressure. Option A,C,D will not be affected by pressure decrease
