Calculation of the conversion rate of SO_2 & CO and the absorption rate of SO_3 & CO_2

A group of new formulae is recommended, not only for the calculation of the conversion rate of SO\-2 and the absorption rate of SO\-3, but also for the calculation of the conversion rate of CO and the absorption rate of CO\-2, further for all the calculation of abovementioned indexes when SO\-2,SO\-3,CO,CO\-2,O\-2 and N\-2 exist together in the system in production of sulfuric acid.
