SO\(_3\) is not directly dissolved in water in the industrial preparation of H\(_2\)SO\(_4\) by the contact process because

• A SO\(_3\) is an acidic gas
• B Acid is usually added to water and not water to acid
• C The reaction between SO\(_3\) and water is violently exothermic
• D SO\(_3\) does not dissolve readily in water
