Equilibrium

Rate of Reaction: 2P + Q ⇌ P₂Q

Given: Rate of formation of P₂Q is

From the stoichiometry:

So, the rate of disappearance of P:

And the rate of disappearance of Q:

But disappearance rates are negative:

Correct Answer: -0.48 mol dm^-3s^-1 and -0.24 mol dm^-3s^-1

Equilibrium Constant for Ammonia Formation

Reaction:

Given concentrations at equilibrium:

Equilibrium constant expression:

Substituting the values:

Simplifying:

Numerator =
Denominator =

Correct Answer: 5 × 10³ mol^-2dm⁶

A molecule is paramagnetic if it has unpaired electrons. Oxygen ( ) has two unpaired electrons in its molecular orbital configuration, making it paramagnetic. Other molecules listed (like and ) do not have unpaired electrons, making them diamagnetic.
Thus, the correct answer is (A).

Molar conductivity is given by: where is the conductivity and is the concentration.
Given:
- ,
- .
Thus: Thus, the correct answer is (E).

When lanthanides (Ln) react with carbon at high temperatures (2773K), they form products with a general formula of , a carbide.
Thus, the correct answer is (D).

The Wacker process is an important method in organic chemistry for the oxidation of alkenes to aldehydes and ketones. The catalyst used in the Wacker process is PdCl (palladium chloride), typically in combination with CuCl.
Thus, the correct answer is (B).

The given structure HOCH (CH ) CH COCH has a hydroxyl group at position 7 and a ketone group at position 2 on the 7-carbon chain. Therefore, the IUPAC name is 7-hydroxyheptan-2-one.
Thus, the correct answer is (B).

In Kolbe's electrolytic method, fatty acids undergo decarboxylation at the anode, leading to the formation of alkane radicals. The acetate ion does not accept electrons to form a free radical, so statement (D) is incorrect.
Thus, the correct answer is (D).
