Solution

(i) Gibbs energy remains unchanged on adding the catalyst.

(ii) Activation energy of the reaction is lowered on adding the catalyst.

Solution

Both physisorption and chemisorption are surface phenomena that increase surface area during the adsorption process.

Solution

Manganese belongs to group number 7 and its oxidation state in MnO₄ ⁻/KMnO₄ is also +7
i.e., KMnO4
1 + x + 4 (-2) = 0
⇒ 1 + x – 8 = 0
⇒ x = 7
Hence, the formula of the oxo-anion is KMnO4.

Solution

BrCH₂(CH₃)C = CH₂

Solution

(i) Abnormal molar mass : When the molecular mass of a substance as determined by studying any of the colligative properties is different than the theoretically expected value, then the substance will have abnormal molecular mass.

(ii) Van’t Hoff factor: van't Hoff's factor (i) is defined as the ratio of the observed colligative property to the calculated colligative property.
i = Observed colligative property / Calculated colligative property
Observed colligative property ∝ 1/Molar Mass
i = Mc/Mo
Van't Hoff's factor (i) represents the extent of association (or) dissociation of a solute.

Solution

(i)F₂ +2Cl⁻ →2F– +Cl₂
(ii) 2XeF₂ + 2H₂O → 2Xe + 4HF + O₂

OR

(i) MnO₂ + 4HCl → MnCl₂ + Cl₂ + 2H₂O
(ii) PCl₅ → PCl₃ + Cl₂
