2. Imagine you run a reaction whose free energy of activation (AG*) is 18 kcal/mol. If it were a first order reaction, its’ half life (the time for half the starting material to go away) or half the product to form (assuming a 100% yield) would by In2/k where k is the rate constant. How long will it take for the reaction to be done if you run the reaction in an ice-salt bath at room temperature (20 °C) if the rate constant were 1 x 104/sec?
A first-order reaction is 40.0% complete at the end of 39.1 minutes. What is the value of the rate constant (in min-1)
Half-life equation for first-order reactions: where t₁/2 is the half-life in seconds (s), and k is the rate constant in inverse seconds (s-¹). To calculate the half-life, plug the value for k into the half-life equation and solve. What is the half-life of a first-order reaction with a rate constant of 7.80x10-4 s-¹?
