In Haber’s process, hydrogen is obtained by reacting methane with steam in presence of NiO as catalyst. The process is known as steam reforming. Why is it necessary to remove CO when ammonia is obtained by Haber’s process?

Mention the conditions required to maximise the yield of ammonia in its synthesis by Haber’s process.

Name the catalyst and the promoter used in Haber's process for manufacture of ammonia.

When electricity is passed through an aqueous solution of sodium chloride, three products are obtained. Why is it’s the process called chlor alkali?

Consider the following half-cell reaction and associated standerd half-cell potentials and determine the maximum voltage thatr can be obtained by combination resulting in spontenous process : AuBr_(4)^(-)(aq)+3e^(-)toAu(s)+4BR^(-)(aq), E^(@)=-086V Eu^(3+)(aq)+e^(-)toEu^(2+)(aq), E^(@)=-043V Sn^(2+)(aq)+2e^(-)toSn(s), E^(@)=-0.14V IO^(-)(aq)+H_(2)O(l)+2e^(-)toI^(-)(aq)+2OH^(-), E^(@)=+0.49V
