A reaction has the following initial rates recorded for different concentrations:
1. [A] = 1M, [B] = 1M, Rate = 0.1 M/s
2. [A] = 2M, [B] = 1M, Rate = 0.4 M/s
3. [A] = 1M, [B] = 2M, Rate = 0.4 M/s
Determine the rate law for the reaction.
💡 Hint: Compare how each change in concentration alters the rate.
Explain why the rates calculated from the initial rate method might differ from those calculated later in the reaction.
💡 Hint: Consider what happens as reactants are used up during the reaction.
