Which of the following statements are correct?
(A) A solution which obeys Raoult's law strictly is called an ideal solution.
(B) A solution which shows deviations from Raoult's law is called a real solution.
(C) If \(T_b\) is the boiling point of the solvent and \(T\) is the boiling point of the solution, then the difference in boiling points (\(\Delta T_b = T_b - T\)) is called elevation of boiling point.
(D) The elevation of boiling point is related to the lowering of vapor pressure.

Read the passage carefully and answer the questions
Sodium dichromate \(Na _2 Cr _2 O _7\) and Potassium dichromate \(K _2 Cr _2 O _7\) are strong oxidizing agents; in acidic solution, its oxidising action can be represented as follows :
\(Cr _2 O _7^{2-}+14 H ^{+}+6 e^{-} \rightarrow 2 Cr ^{3+}+7 H _2 O \left( E ^{\circ}=1.33 V\right)\)
The chromates and dichromates are interconvertible in aqueous solution depending upon pH of the solution.
The chromate ion is tetrahedral whereas the dichromate ion consists of two tetrahedra sharing one corner with \(Cr - O - Cr\) bond angle of \(126^{\circ}\)
Potassium permanganate is prepared by fusion of \(MnO _2\) with an alkali metal hydroxide and an oxidising agent like \(KNO _3\).
This produces the dark green \(K _2 MnO _4\) which disproportionates in a neutral or acidic solution to give permanganate. It is a strong oxidizing agent. Hydrogen ion concentration of the solution plays
an important part in the reduction of permanganate to manganate, manganese dioxide and manganese(II) salt.
Potassium permanganate forms dark purple (almost black) crystals which are isostructural with those of \(KClO _4\).
The salt is not very soluble in water \((6.4 g / 100 g\) of water at 293 K ), but when heated it decomposes at 513 K .
Alkaline/neutral \(KMnO _4\) oxidizes iodide ( \(I ^{-}\)) ion to

Which of the following aze correct about the linear programming problem (LPP)?
(A) The objective function is always linear.
(B) A corner point of a feasible region is a polut in the region which is the intersection of two boundary lines.
(C) The common region determined by all the linear constraints of a LPP is called the feasible region.
(D) If an LPP admits optimal solution at two points then its optimal values occurs at an infinite number of points.
