Read the passage carefully and answer the Questions
A homogeneous mixture of two or more than two components has uniform composition and properties. The binary solutions have two components, which may be solid, liquid or gas. The resultant solution has a larger amount of solvent and a smaller amount of solute. The amount of solute in a given amount of solvent decides the concentration of the resulting solution. The concentration can be expressed in various ways, like molarity, molality, normality and mole fraction. The molality of a 1 liter aqueous solution of \(93 \backslash \% H _2 SO _4\) (mass/volume) is:
(Given: density of the solution \(=1.84 g mL ^{-1}\), molar mass of \(\left.H _2 SO _4=98 g mol ^{-1}\right)\)

Answer the question on the basis of passage given below:
Adsorption is the phenomenon of attracting and retaining the molecules of a substance on the surface of a solid resulting into a higher concentration on the surface than in the bulk. The substance adsorbed is known as adsorbate and the substance on which adsorption takes place is called adsorbent. In physisorption adsorbate is held to the adsorbent by weak van der Waals forces and in chemisorption by strong chemical bond.In the given reaction, the catalyst used is:
\(2 H_2(g)+O_2(g) \longrightarrow 2 H_2 O(l)\)

The unit of E_cell is
