✦ Synopsis

A modified version of the gram theory was used to analyse the effect of temperature on the sulfatlon reactlon The theory combines the Influence of temperature on the gram size, Its effect on the rate of transport of SO, and the chemical reactlon An efficient numerical procedure 1s presented for solvmg the model equations which take mto account the radial gradlent of the effective dlffuslvlty m a particle
