Question 1 answer A student investigated the rate of reaction between calcium carbonate (marble chips) and hydrochloric acid. The student had collected 30 cm 3 of gas produced after 15 seconds. Calculate the mean rate of reaction from 0 to 15 seconds. Mean rate of reaction = quantity of product formed time taken Mean rate of reaction = 30 15. 10 Reaction rates and equilibrium Exam-style mark schemeOCR Chemistry A Questionnumber Answer Marks Guidance 4 b iii Forward and backwards reaction rate increase by the same amount. No effect (on equilibrium position). M1 A1 4 c Catalyst lowers the activation energy / energyrequirement or means lower temperature needed..
