![A reaction is 2nd order with respect to [ Reactant A ]. If the rate
constant from the equation of the trendline in Excel is 3.22 x 10
3
(units deliberately omitted), and the initial concentration is
0.437 M A, then what is the[ Reactant A] (in M A) at 300
minutes?
IMPORTANT: When entering your answer:
• Enter the number only (no units)
• Do not leave any spaces
• Use a leading zero before the decimal when necessary
• Report your number to 3 decimal places (regardless of the
significant figures)
• Correctly round your answer to the 3rd decimal place (margin
of allowed error is only + 0.001, so always use un-rounded
numbers in your calculations). If the last digits are zeros they
will not display once you click away, but the answer will still
be marked correct.

Expert Solution
Step 1
For a second-order reaction, the reaction rate is proportional to the square of the concentration of the reactant. The rate law is . Here, k is the reaction rate constant and CA is the concentration of reactant A at any instant of time. Also, it is known that the rate of the reaction is a change in concentration per unit of time. It is therefore equals to .
