Question 1 / 1

AQA Jan 2013 Paper 2 Q2 do not write outside the box a study of equilibrium is important for understanding chemical reactions a state le chatelier s principle mark extra space b catalysts play an important role in many reactions b i state the meaning of the term catalyst explain in general terms how catalysts work meaning of the term catalyst how catalysts work marks extra space b ii state the effect if any of a catalyst on the time taken to reach equilibrium mark b iii state the effect if any of a catalyst on the position of an equilibrium mark wmp jan chem do not write outside the box c consider the following equilibrium reactions h g l g hl g co g h g ch oh g h o g n o g n g h g no g nh g c h g h o g ch ch oh g h kj mol in each of parts c i to c v you should record in the box one of the letters p q r s or t that corresponds to the equilibrium that best fits the information provided you may use each letter once more than once or not at all c i a decrease in temperature at constant pressure shifts the position of this equilibrium from right to left c ii this equilibrium uses concentrated phosphoric acid as a catalyst in a hydration reaction mark mark c iii a decrease in pressure at constant temperature shifts the position of this equilibrium from left to right c iv there is no change in the position of this equilibrium when the pressure is increased at constant temperature mark c v an increase in the concentration of steam at constant temperature and constant pressure shifts the position of this equilibrium from right to left mark mark turn over wmp jan chem
