The JAVA applet below plots the molarities of the reactant A and product B over time as the reaction

proceeds to completion. Select an energy of activation ( E_a ) and a temperature in degrees Kelvin in the pop-up menus. Enter the initial molarity of A (value must be >= 0 and <= 5.0), and then click the "Enter" button. Plots of the molarities of A and B versus time are displayed along with the inital ( at time = 0 seconds ) rate of consumption of A (-d[A]/dt), the rate of consumption of A at 4 and 15 seconds, and the rate of formation of B (d[B]/dt) at 4 seconds.

    Use the applet in the design and performance of experiments to answer the following questions.

1. How does the initial rate of consumption of A change with a change in the initial molarity of A?
Begin by selecting Ea(1) and 298 K. Enter 5.0 M for [A]_in.
2. How and why does the rate of consumption of A change with time?
3. Is the rate of formation of B at 4 seconds equal to the rate of consumption of A at 4 seconds?
4. How does the initial rate of consumption of A change with a change in the energy of activation, E_a?
5. How does the initial rate of consumption of A change with a change in the temperature?
6. What is the rate law for the reaction?
7. What is the value of the activation energy Ea(2)?
