NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Imagine a diagram showing two beakers, labeled beaker 1 and beaker 3, each containing a brown gas mixture of NO2 and N2O4. If the temperature in beaker 1 is lowered and the temperature in beaker 3 is raised, what change in color intensity would you expect in each beaker?
A
Beaker 1 becomes less brown, beaker 3 becomes more brown.
B
Beaker 1 becomes more brown, beaker 3 becomes less brown.
C
Both beaker 1 and beaker 3 become more brown.
D
Both beaker 1 and beaker 3 become less brown.
Correct Answer
Option A
Detailed Explanation
Lowering the temperature in beaker 1 favors the exothermic formation of N2O4, reducing the brown color due to NO2. Raising the temperature in beaker 3 favors the endothermic reverse reaction, increasing the brown color.
