Process which is antithetical to fertilization is

In order to maintain soil fertility , it is necessary to add containing nitrogen , phosphorous and potassium in the form of manures. Manures are two type they are a ) Natural and b) Artificial , Artifical manures are chemical compounds obtained by artificial mean containing N,P or K. These chemical compounds are generally called fertilizers. The chemical substance which are added to the soil as to make up the deficiency of essential elements are called fertilizers. Every chemical compounds of N,P , & K can be used as fertilizer and it must have chracteristic properties. Fertilizers are classified according to the element (N,P or K) which they are supplied to the soild. A compound of N,H,C and 'O' which is used as a fertilizer

The amount of energy released when an electron is added to an isolated gaseous atom to produce a monovalent anion is called electron affinity or first electron affinity or electron gain enthalpy. The first electron is given a negative sign as the addition of an electron to a neutral atom is an exoergic process. The addition of electron to A^(-1) requires energy to overcome the force of repulsion. Thus, the second electron affinity is an endoergic process. The magnitude of electron affinity depends on a number of factors such as (i) atomic size (ii) effective nuclear charge (iii) screening effect (iv) half and fully filled orbitals and (v) shape of orbital. In general, electron affinity increases as the atomic radii decrease in a period. However, there are exceptions when the atoms have stable configurations. In a group, electron affinity decreases as the size increases. However, the members of 3rd period have somewhat higher values than the members in the 2nd period of the same subgroups. Which of the following processes is endoergic in nature ?

Passage: When all the coefficients in a balanced chemical equation are multiplied by a constant factor X the equilibrium constant (originally K) becomes K^J . Similarly, when balanced equations are added together, the equilibrium constant for the combined process is equal to the product of the equilibrium constants for each step. Equilibrium constant of the reversed reaction is numerically equal to the reciprocal of the equilibrium constant of the original equation. Unit of K_p = ("atm")^(Deltan) , Unit of K_c =("mol" L^(-1))^(Deltan) Consider the reactions: (i) CO_((g))+H_2O_((g)) harr CO_(2(g))+H_(2(g)) , K_1 (ii) CH_(4(g))+H_2O_((g)) harr CO_((g))+3H_(2(g)) , K_2 (iii) CH_(4(g))+2H_2O_((g)) harr CO_(2(g))+4H_(2(g)) , K_3 Which of the following is correct ?
