a) The reaction A(ag) → B(aq) is first-order with respect to A(aq). The concentration of A(aq) after 100.0 s of reaction is 0.555 M. The concentration of A(aq) after a further 400.0 s (500.0 s total) is 0.333 M. What will be the concentration of A(aq) after a further 500.0 s (1000.0 s total)? What is the half-life of the reaction? The temperature is 25.0 °C throughout the reaction. b) The reaction 2 A(aq) → B(aq) is second-order with respect to A(aq). When the concentration of A(ag) is 0.150 M and the temperature is 25.0 °C, the reaction rate is 0.1350 M/s. If we increase the concentration of A(aq) to 0.450 M and lower the temperature to 5.0 °C, the rate of reaction becomes 0.0300 M/s. What is the activation energy for this reaction?
