1.30 A method used to investigate the rate of reaction of calcium carbonate with dilute hydrochloric acid under different conditions is shown. ● Place 50 cm3 of dilute hydrochloric acid in a conical flask. ● Add a known volume of water to the conical flask. ● Heat the conical flask to the required temperature. ● Add 1.0 g of calcium carbonate to the conical flask. ● Measure the time taken for the reaction to finish. Which volume of water and which temperature gives the shortest time taken for the reaction to finish? volume of water added / cm3 temperature / °C A 10 30 B 10 50 C 40 30 D 40 50
