Altering conditions - Pressure 2.0 / 5 based on 1 rating ? ChemistryEquilibriumGCSEAQA Created by: CharCreated on: 16-05-13 18:27 Changing pressure can affect what? Reversible reactions involving gases at equilibrium 1 of 7 If the pressure is increased, the position of equilibrium will... Shift to try and reduce the pressure 2 of 7 If the forward reaction produces more molecules of gas... An INCREASE in PRESSURE will DECREASE the amount of products formed 3 of 7 If the forward reaction produces more molecules of gas... A DECREASE in PRESSURE will INCREASE the amount of products formed 4 of 7 If the forward reaction produces fewer molecules of gas... An INCREASE in PRESSURE will INCREASE the amount of products formed 5 of 7 If the forward reaction produces fewer molecules of gas... A DECREASE in PRESSURE will DECREASE the amount of products formed 6 of 7 For example in 2NO2 <---> N204, there are more gaseous REACTANT molecules than gaseous PRODUCT molecules Therefore, INCREASING the pressure will INCREASE the amount of ammonia 7 of 7
