Acidified potassium permanganate is an oxidising agent so compound Y is produced from the oxidation of X. 2019 . Isomer A can be distinguished from isomer B by their reaction with acidified potassium permanganate. A catalyst provides an alternative reaction pathway for a reaction that has a lower activation energy. Below are the answers and worked solutions to this year’s Chemistry HSC Exam. Since the rate of the forward reaction is slower than the reverse reaction, the equilibrium is shifted left, resulting in an increase in the concentration of CO. Over time, as more CO and H2O are formed and CO2 and H2 concentrations decrease, the rate of the forward reaction increases while the rate of the reverse reaction decreases until the rates become equal again and all the concentrations remain constant.
