The overall order of a reaction is determined by summing the exponents of the concentration terms in the rate law.
In this case, the rate law is given as \( \text{Rate} = k[A]^2[B] \).
The exponent of \( [A] \) is 2 and the exponent of \( [B] \) is 1.
Therefore, the overall order is \( 2 + 1 = 3 \).
Consider the following compounds. Arrange these compounds in a n increasing order of reactivity with nitrating mixture. The correct order is : 
In the given figure, the blocks $A$, $B$ and $C$ weigh $4\,\text{kg}$, $6\,\text{kg}$ and $8\,\text{kg}$ respectively. The coefficient of sliding friction between any two surfaces is $0.5$. The force $\vec{F}$ required to slide the block $C$ with constant speed is ___ N.
(Given: $g = 10\,\text{m s}^{-2}$) 
Method used for separation of mixture of products (B and C) obtained in the following reaction is:
