What is the product of following reaction ?

At 35^oC, the vapour pressure of CS₂ is 512 mm. Hg and that of acetone is 344 mm Hg. A solution of CS₂ in acetone has a total vapour pressure of 600 mm Hg. The false statement amongst the following is :

The number of orbitals associated with quantum number n = 5, m_s = +$${1 \over 2}$$ is :

For the reaction :

A($$l$$) $$ \to $$ 2B(g)

$$\Delta U = 2.1\,kcal,\,\Delta S = 20\,cal\,{K^{ - 1}}$$ at 300 K

Hence $$\Delta $$G in kcal is :
