The balanced chemical equations involved, when ${SO}_{3}$ is converted to sulphuric acid using the contact process, are the following.

${SO}_{3} + H_{2} S O_{4} \to$ $H_{2} S_{2} O_{7}$

${H_{2} S_{2} O_{7} + H_{2} O \to}_{} 2 {H_{2} S O_{4}}_{}$

Accepted Answer

The given statement is true.concept - We are aware that sulphuric acid is created by the contact process. Sulphur dioxide is the intermediate product of three reactions that take place in this process. In the contact process,  SO3 react with sulphuric acid to form oleum and finally, oleum is diluted by water to to form sulphuric acid.The production of sulphur dioxide is what takes place in the first stage. Sulfur and oxygen combine in this reaction, producing sulphur dioxide as a byproduct.S+O2→ SO2The reaction will continue in the second step when sulphur dioxide will be used, and it will react in the presence of oxygen gas. Vanadium oxide serves as a catalyst in this process. As can be seen, sulphur trioxide is the end result.2SO2+O2→ 2SO3Sulfur trioxide is used in the third phase, at which time sulphur dioxide and sulfuric acid will react. Oleum is created during this process. SO3+ H2SO4→  H2S2O7The third phase now includes the second reaction, which means that it will continue to occur while there is water present. Concentrated sulfuric acid is created during this phase.H2S2O7+H2O →2 H2SO4Hence, the correct answer is option 1.
