) The reaction A(aq) → B(aq) is a first order reaction with respect to A(aq). The concen-
tration of A (aq) after 100.0 s of reaction is 0.555 M. The concentration of A(aq) after 300.0 s is 0.333
M. What was the initial concentration of A(aq)? The temperature is 25.0°C throughout.
(b)..
) The reaction 2 A(aq) → B(aq) + C(aq) is a second order reaction with respect to A(aq).
When the concentration of A(aq) is 0.200 M and the temperature is 25.0°C, the rate of reaction
is 0.00100 M/s. When we increase the concentration of A(aq) to 0.600 M and we increase the
temperature to 50.0°C, the rate of reaction is 0.06300 M/s. What is the activation energy for this
reaction?
