उत्तर
Balanced equation for the reaction between Zinc and dilute sulphuric acid is :
Zn + H2SO4 → ZnSO4 + H2
(i) The purpose of contact process is to manufacture sulphuric acid.
(ii) Vanadium pentoxide is the catalyst used in the contact process.
(iii) Balanced equation for the reaction in the contact process which takes place in the presence of catalyst is:
2SO2 + O2 ⇌ 2SO3 + Heat
