Sulphuric acid is probably the most important industrial chemical because it is used in so many industrial processes to produce or purify other chemicals. it can be produced by a three step process: sulphur is burnt in air to give sulphur dioxide. sulphur dioxide is converted to sulphur trioxide by passing the sulphur dioxide over a catalyst in the presence of oxygen at high temperatures. sulphur trioxide is reacted with water to produce sulphuric acid. if the three steps gave yields as listed below, and you start with 1.00 x 103 kg of sulphur (assume other reagents are in excess), how much sulphuric acid can be produced? reaction % yield s + o2 \longrightarrow ⟶ so2 92.5% so2 + o2 \longrightarrow ⟶ so3 72.6% so3 + h2o \longrightarrow ⟶ h2so4 98.2%
