Answer the following questions (Do any two) :
(a)
Identify the order of reaction from the following unit for its rate constant : $\displaystyle \mathrm{Lmol}^{-1} \mathrm{~s}^{-1}$
(b)
The conversion of molecules A to B follow second order kinetics. If concentration of A is increased to three times, how will it affect the rate of formation of B?
(c)
Write the expression of integrated rate equation for zero order reaction.
Marking-scheme solution
(a) Second order
(b) Nine or $\displaystyle 9$ times
(c) \(\displaystyle \mathrm{k}=\frac{[R]_{0}-[R]}{t}\)
