For a chemical reaction A → B, the rate doubles when the concentration of A is increased four times. The order of reaction is
Rate ∠[A]â¿: solve for n.
2
1
1/2
Zero
2 = 4⿠→ n = 1/2, so order is 1/2.
Consider the following compounds. Arrange these compounds in a n increasing order of reactivity with nitrating mixture. The correct order is : 
A carpenter needs to make a wooden cuboidal box, closed from all sides, which has a square base and fixed volume. Since he is short of the paint required to paint the box on completion, he wants the surface area to be minimum.
On the basis of the above information, answer the following questions :
Find \( \frac{dS}{dx} \).
