Please answer these questions on your Page 12 (a) The reaction A(aq) → B(aq) is first order with respect to A(aq). The concentration of A(aq) after 200.0 s of reaction is 0.666 M. The concentration of A(aq) after another 500.0 s (so 700.0 in total) is 0.555 M. What will the concentration of A(aq) be after another 300.0 s (so 1000.0 s in total)? The temperature is 25.0°C.

(a)
The reaction A(aq) → B(aq) is first order with respect to A(aq). The concentration of
A(aq) after 200.0 s of reaction is 0.666 M. The concentration of A(aq) after another 500.0 s (so 700.0
s in total) is 0.555 M. What will the concentration of A(aq) be after another 300.0 s (so 1000.0 s in
total)? The temperature is 25.0°C.
(b)
The reaction 2 A(aq) → B(aq) + C(aq) is a first order reaction with respect to A(aq).
When the concentration of A(aq) is 0.500 M at a temperature of 25.0°C, the rate of reaction is 0.00100
M/s. When we reduce the concentration of A(aq) to 0.100 M and we increase the temperature to
75.0°C, the rate of reaction is 0.00700 M/s. What is the activation energy for this reaction?
