Find out the odd one. 
Let’s analyze the given options one by one:
- Option A: The shape inside the box in option A has a triangle and a circle, which is different from other shapes that involve a combination of different geometric shapes (square, triangle, and circle).
- Option B: The shapes in the box involve a circle, square, and triangle, and follow a similar pattern as the other options.
- Option C: Similarly, option C involves different shapes (circle, square, and triangle) in different orientations.
- Option D: This option is the most different as it involves a circle and square, with the other shapes (triangle) placed differently.
Thus, option A is the odd one out as it doesn't follow the same pattern of shapes as the others.
Final Answer: (D) A
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)
A black body is at a temperature of 2880 K. The energy of radiation emitted by this body with wavelength between 499 nm and 500 nm is U1, between 999 nm and 1000 nm is U2 and between 1499 nm and 1500 nm is U3. The Wien's constant, b = 2.88×106 nm-K. Then,
