Differential form of the rate equation is

$\frac{{dx}}{{dt}} = k\left[ P \right]{\left[ Q \right]^{0.5}}{\left[ R \right]^{0.5}}$ 

Which statement about the above equation is wrong?

$(a)$ Write general reaction and derive the units of rate constant. $(b)$ Based on that write the rate constant for zero, first and $2^{nd}$ order reaction.

Following is the rate constant of reaction what is the overall order of reaction ?

$(a)$ $2.418 \times 10^{-5}\,hr ^{-1}$

$(b)$ $7.1 \times 10^{-4} \,atm \,s ^{-1}$

For which type of reactions, order and molecularity have the same value ?

If the half life period of a reaction is inversely proportional to the initial concentration, the order of the reaction is

The variation of the rate of an enzyme catalyzed reaction with substrate concentration is correctly represented by graph
