AB reaction is elementary in both directions and carried out in a batch reactor. Initially, the concentration of A is 1mol/L and B is absent. The equilibrium conversion of the reaction is 0.75 and 50% of A is converted 10 minutes after the start of the reaction. - Suggest a rate expression for this reaction. - Calculate how long it takes for 70% of A to be converted. - What is the time it takes to reach 80% conversion
