AQA AS Chemistry Paper 2 – Organic and Physical Chemistry Predicted Paper 2023 Name …………………………………………………………………… Date ………………… ... 1 hour 30 minutes allowed You should have access to the AQA insert (periodic table and data sheet) to help with answering the questions. You should spend around 65 minutes on section A and 25 minutes on section B. Grade boundaries These are VERY rough guesses! Getting a C on this paper does not guarantee you the same mark in the exam. • A – 80 • B – 70 • C – 60 • D – 50 • E - 40 SECTION A 01 A chemist carries out an investigation on the equilibrium system shown below. 2X(g) + Y(g) ⇌ 2Z(g) This reaction can be carried out so that the position of the equilibrium is completely on the right-hand side, at a temperature of 500°C and 2 atmosphere pressures in the presence of a V2O5 catalyst. Then the chemist carries out this reaction at a temperature of 500°C and 2 atmospheres pressure. He does not use the catalyst. 01.1 Predict the changes, if any to each of the following. i. Position of the equilibrium. [1 mark] ii. Rate of the backward reaction. [Show More]
