For the reaction: $A_2(g) \rightleftharpoons B_2(g)$

The equilibrium constant $K_c$ is given as 99.0. In a 1 L closed flask, two moles of $B_2(g)$ is heated to $T(K)$. What is the concentration of $B_2(g)$ (in mol L$^{-1}$) at equilibrium?

Identify the incorrect set from the following:

Identify the molecule for which the enthalpy of atomization $ (\Delta_a H^\circ) $ and bond dissociation enthalpy $ (\Delta_{\text{bond}} H^\circ) $ are not equal.

In case of diffraction, if $ a $ is a slit width and $ \lambda $ is the wavelength of the incident light, then the required condition for diffraction to take place is:

In Young’s double slit experiment, two slits are placed 2 mm from each other. The interference pattern is observed on a screen placed 2 m from the plane of the slits. Then the fringe width for a light of wavelength 400 nm is:

Three particles of each mass $ m $ are kept at the three vertices of an equilateral triangle of side $ 1 $. The moment of inertia of the system of the particles about any side of the triangle is:

A block has dimensions 1 cm, 2 cm, and 3 cm. The ratio of the maximum resistance to minimum resistance between any pair of opposite faces of the block is:

A current of $6A$ enters one corner $P$ of an equilateral triangle $PQR$ having three wires of resistance $2 \Omega$ each and leaves by the corner $R$ as shown in figure. Then the currents $I_1$ and $I_2$ are respectively

The value of shunt resistance that allows only 10% of the main current through the galvanometer of resistance $ 99 \Omega $ is:

If the origin is shifted to a point $ P $ by the translation of axes to remove the $ y $-term from the equation $ x^2 - y^2 + 2y - 1 = 0 $, then the transformed equation of it is:

Number of deactivating groups among: $ -Cl, -SO_3H, -OH, -NHC_2H_5, -COOCH_3, -CH_3 $

A line $ L $ intersects the lines $ 3x - 2y - 1 = 0 $ and $ x + 2y + 1 = 0 $ at the points $ A $ and $ B $. If the point $ (1,2) $ bisects the line segment $ AB $ and $ \frac{a}{b} x + \frac{b}{a} y = 1 $ is the equation of the line $ L $, then $ a + 2b + 1 = ? $

The real valued function $ f: \mathbb{R} \to \left[ \frac{5}{2}, \infty \right) $ defined by $ f(x) = \left| 2x + 1 \right| + \left| x - 2 \right| $ is:
