Activation energy is the amount of energy required to initiate a chemical reaction. The activation energy can be determined from reaction rate constants at different temperatures by the equation. ln(k 2 /k 1) = E a /R x (1/T 1 - 1/T 2).
Robins eat different types of food depending not only on the time of year, but even time of day. They eat earthworms early in the day and more fruit later in the day. Because they forage largely on lawns, they are vulnerable to pesticide poisoning and can be an important indicator of chemical pollution.
