# For the reaction $\dpi{100} A+2B\rightarrow C,$ rate is given by $\dpi{100} R=\left [ A \right ]\left [ B \right ]^{2}$  then the order of the reaction is Option 1) 3 Option 2) 6 Option 3) 5 Option 4) 7

As we learnt in

Order of a Reaction -

The order of a reaction is determined as the sum of the powers of the concentration terms that appear in the experimental rate equation. It is an experimental quantity.

- wherein

Formula: $aA+bB\rightarrow cC+dD$

$r=K[A]^{a}[B]^{b}$

$order=(a+b)$

$\therefore$     Order has relation with stoichiometry & is determined experimentally. It can be zero/fraction/negative/positive

for reaction $A+2B\rightarrow C$

Rate = $k\left [ A \right ]\left [ B \right ]^{2}}$

order =1+2=3
