CLICK HERE TO SEE QUESTION 3 QUESTION 3 3.1 A series оf experiments is cаrried оut tо investigаte the effect of different fаctors on the rate of a chemical reaction between sulfuric acid and zinc. The balanced chemical equation for the reaction is: Four different experiments are carried out using the conditions given in the table below: In each of the experiments, the same volume of sulfuric acid and the same mass of zinc are used. The zinc is always in excess and completely covered by sulfuric acid The reaction rate for each experiment is monitored by measuring the volume of hydrogen gas produced at STP against time. The results of the four experiments are shown in the graph below. 3.1.1 Explain why graph A flattens out after t=25s (1) 3.1.2 Name which of the graphs, B, C or D corresponds to: Experiment 2 Experiment 3 Experiment 4 (3) 3.1.3 Explain the answer to Question 3.1.2 C with reference to the collision theory. (3) 3.1.4 With reference to reaction rate and the collision theory, explain one difference and one similarity between Experiment 1 and Experiment 2. (2) 3.1.5 Use the information from graph A to calculate the average reaction rate of the reaction in Experiment 1 over the first 25 s. Give your answer in units of moles of H2 gas per second (mol.s -1 ) to four decimal places. (4) [13]
