Order of a reaction:
For a given reaction:
\mathrm{a A+b B+c C \rightarrow \text { Products } }
If,
Rate \mathrm{\propto[A]^p[B]^q[C]^r }
Overall order of the reaction is :
(p+q+r)
where,
\mathrm{p } : order of reaction with respect to A
\mathrm{q} : order of reaction with respect to B
\mathrm{r} : order of reaction with respect to C
For
\mathrm{P(g)+Q(g)+R(g) \rightarrow S(g)+T(g)}
Rate is,

\mathrm{R=K[P]^3[Q]^{-1}[R]^0 .}

Thus, order of reactions is
3+(-1)+0=2

Also,
Order of reeaction with respect to P is 3
Order of reeaction with respect to Q is -1
Order of reeaction with respect to R is 0.
