Suppose you are carrying out a reaction in the laboratory and need to convert the 1.00 mole of reactant X into products. This reaction shows first-order kinetics, and the reaction mixture has a constant volume of 1.00 liter.
- At 1:00pm, you start the reaction at 25°C with 1.00 moles of reactant X.
- At 2:00pm, you find that 0.60moles of reactant X remain. You immediately increase the temperature of the reaction mixture to 35°C.
- At 3:00pm, you discover that0.20 moles of reactant X are still present. You want to be able to finish the reaction by 4:00pm, but you cannot stop the reaction until only 0.01 moles of reactant X remain. You must increase the temperature again.
Determine the minimum temperature needed to complete the reaction by 4:00pm?
