Chemistry - Chemical Equilibrium Question with Solution | TestHub
Match the change in Column I with its effect on the equilibrium constant in Column II (a Column I entry may match more than one Column II entry):
Column I (Change) | Column II (Effect on ) |
|---|---|
(P) Temperature raised for an exothermic reaction | (1) increases |
(Q) Temperature raised for an endothermic reaction | (2) decreases |
(R) A catalyst is added | (3) remains the same |
(S) Volume of the container is reduced | (4) depends on temperature only |
Choose the option with the correct matching:
Options:
Answer:
Solution:
is a function of temperature only.
(P) Exothermic: decreases with T (2) and depends on T only (4).
(Q) Endothermic: increases with T (1) and depends on T only (4).
(R) A catalyst does not change (3), which depends on T only (4).
(S) Changing the volume does not change (3, 4).
Correct matching: P to 2,4; Q to 1,4; R to 3,4; S to 3,4. Answer: (D).
