Q. The rate constant of reaction $2 A + B \to C$ is $2.57 \times 10^{-5} L\, mole^{-1} sec^{-1}$ after $10 sec, 2.65 \times 10^{-5} L\, mole^{-1} sec^{-1}$ after $20 sec$ and $2.55 \times 10^{-5} L\, mole^{-1} sec^{-1}$ after $30 sec.$ The order of the reaction is:

Chemical Kinetics

Solution:

$2A + B \to C$
Unit of $k = lit mole^{-1} sec^{-1}$
so order of reaction $= 2.$
