Answer to Question #105944 in General Chemistry for Lillian

Question

For a generic A→B, what quantity, when graphed versus time, will yield a straight line?
Match the words in the left column to the appropriate blanks in the sentences on the right.

A graph of -------- versus time yields a straight line for a second-order reaction. versus time yields a straight line for a second-order reaction.

Answer 1

The second order reaction is given by $\frac{-dA}{dt}=k[A]^2$

$\frac{-dA}{[A]^2}=kdt$

integrating we get

$\frac{1}{[A]}-\frac{1}{[A]_o}=kt$

Hence graph of inverse of concentration at time t vs time t will give the straight line
