For the reaction $2\mathrm{A}+3\mathrm{B}+\frac{3}{2}\mathrm{C}\to 3\mathrm{P}$   , which statement is correct?

For a given reaction, rate $=-\frac{1}{2}\frac{d{n}_A}{dt}=-\frac{1}{3}\frac{d{n}_B}{dt}=-\frac{2}{3}\frac{d{n}_C}{dt}$

$\text{rate}=\frac{{\mathrm{d}\mathrm{n}}_{\mathrm{A}}}{\mathrm{d}\mathrm{t}}=\frac{2}{3}\frac{{\mathrm{d}\mathrm{n}}_{\mathrm{B}}}{\mathrm{d}\mathrm{t}}=\frac{4}{3}\frac{{\mathrm{d}\mathrm{n}}_{\mathrm{C}}}{\mathrm{d}\mathrm{t}}$
