A pyramid of energy is used to analyze the amount of energy available at each feeding level in a food chain. Using the pyramid a
bove, answer the question: Why is the amount of energy available to the tuna less than the amount available to the mackerel?
There aren't enough zooplankton
There aren't enough phytoplankton
While mackerel are getting energy, they are also using some of it.
If the tuna dies, the mackerel will eat it.

Answer: The rate constant is
Explanation ;
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = ?
t = age of sample = 4.26 min
a = initial amount of the reactant = 2.56 mg
a - x = amount left after decay process = 2.50 mg
Now put all the given values in above equation to calculate the rate constant ,we get
Thus rate constant is [tex]0.334s^{-1}
