Multiple Choice Questions On Physical Chemistry

Question 1.

For the half cell Cl^–1/Pt(Cl₂), the value of (E – E°):

decreases as [Cl^–1] increases
increases as [Cl^–1] increases
remains constant as [Cl^–1] increases
cannot be predicted

Question 2.

A. 141. 25 dm³

B. 100. 3 dm³

C. 6. 27 dm³

D. 73. 28 dm³

Question 3.

In the context of quantitative estimation of aqueous Fe(NO₃)_2, identify the incorrect statement.

can be used in aqueous HCl
can be used in aqueous H₂SO₄
can be used in aqueous H₂SO₄
can be used in aqueous HCl

Question 4.

The gaseous reaction A → 2B + C is found to be first order at 100°. If it starts with pure A, at the end of 10 min, the total pressure of the system is 308 mm and after a long time, it is 360 mm. Calculate the partial pressure of A at the end of 10 min.

26mm
94mm
36mm
176mm

Question 5.

The isomerisation of cis to trans-but-2ene, C₄H₈, follows a Lindemann mechanism. At high pressure, for the isomerisation process, the pseudo first-order rate constant is 2 × 10^–5 at 500°C. Also, at a given temperature, the collisional action with an efficiency that is 10¹¹ times slower than that of collisional deactivation, determines the rate constant for the final step of the mechanism

B. 100. 3 dm³

C. 6. 27 dm³

D.73. 28 dm³

Question 8.

HF > H₂O > NH₃ > CH₄

_A.

B. OH^-

^C. F–
