What is the order of the reaction with respect to the reactant?
Homework Answers
Answer #1
If we plot the graph between (1/C) versus time we will get straight line.
For second order reaction we have
(1/C) = (1/C0) + kt
Where C is concentration at time t and C0 is initial concentration of reactant. k is rate constant.
If we plot the graph between concentration values versus time then we will get a straight line with intercept (1/C0) and slope k.
Hence the given reaction is second order reaction.

The reaction A→C is first-order in the reactant A and is known
to go to completion. The product C is colored and absorbs light
strongly at 550 nm, while the reactant and intermediates are
colorless. A solution of A was prepared, and the absorbance of C at
550 nm was measured as a function of time. (Note that the
absorbance of C is directly proportional to its concentration.)

Learning Goal: To understand how to use integrated rate laws to
solve for concentration. A car starts at mile marker 145 on a
highway and drives at 55 mi/hr in the direction of decreasing
marker numbers. What mile marker will the car reach after 2 hours?
This problem can easily be solved by calculating how far the car
travels and subtracting that distance from the starting marker of
145. 55 mi/hr×2 hr=110 miles traveled milemarker 145−110
