For chemical reaction , the concentration of reactant was initial taken as 20 molar per liter , after 30 minutes 50% of it remained. If the same reaction is started with concentration of 40 mol/litre , then after 1/2 hour it's concentration remains 20 mol/litre. What conclusion will you draw based on above observation, based on this conclusion what will be the order of reaction ? Answer : Based on the given observations, we can draw the following conclusion and determine the order of the reaction: Conclusion based on observations: 1. Observation 1: When the initial concentration of the reactant is 20 mol/liter, after 30 minutes, 50% of it remains (i.e., 10 mol/liter). This means the half-life (t₁/₂) of the reaction is 30 minutes when the initial concentration is 20 mol/liter. 2. Observation 2: When the same reaction is started with an initial concentration of 40 mol/liter, after 1/2 hour (30 minutes), its concentration remains 20 mol/liter. This means the half-life (t₁/₂) of...
