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.
Argyrol is a medicine used for

The rate constant for the first order reaction is \(60\) \(s^{-1}\). The time taken to reduce the initial concentration of the reactant to its \(1/26^{th}\) value is:
[Given \(\log 26 = 1.4150\)]

Answer the question on basis of passage given below :
The noble gases He to Rn have close shell configuration and are monoatomic gases under normal conditions. Though mostly unreactive, but direct reaction of Xe with \(F_2\) leads to a series of compounds with Xe oxidation numbers \(+2,+4\) and +6 . When certain compounds like phenol and quinol are crystallised in the presence of noble gas such as \(Ar , Kr\) and Xe a category of compound called clathrates are formed. In these the noble gas atoms are trapped in the cavities of the crystal lattices. The compounds which crystallise are known as hosts (H) while the noble gas atoms are called guests ( \(G\) ). The general formula of a clathrate compound is \(n H m G\), where \(n\) is the number of host molecules and m is the number of atoms a molecule of guest.
In what molar ratio must Xe and \(F_2\) be taken to give \(XeF _4\) ?
