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

The correct answer is B. Increase yield of Pcl3

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
