Question 1
Design an experiment to determine the reaction order of a hypothetical reaction A + B → C. Explain how you would systematically vary concentrations and analyze results.
💡 Hint: Think of how controlling variables can help isolate reactions.
Question 2
Given the following data from initial rate experiments:
Experiment 1: [A]=0.1 M, [B]=0.2 M, Rate=0.01 M/s;
Experiment 2: [A]=0.1 M, [B]=0.4 M, Rate=0.04 M/s;
Analyze the data to determine the order of reaction with respect to B.
💡 Hint: Look for multiplicative relationships in rates when concentrations change.
