When sulfur dioxide reacts with water , the product is called sulphurous acid, H2SO3. The balanced equation is expressed in the following manner : SO2 + H2O = H2SO3. There is a one mole to one mole ratio between any of the reactants to product, sulphurous acid.
(missing part of your question): when we have K = 1 x 10^-2 and [A] = 2 M & [B] = 3M & m= 2 & i = 1 So when the rate = K[A]^m [B]^i and when we have m + i = 3 so the order of this reaction is 3 So the unit of K is L^2.mol^-2S^-1 So by substitution: ∴ the rate = (1x 10 ^-2 L^-2.mol^-2S^-1)*(2 mol.L^-1)^2*(3mol.L^-1) = 0.12 mol.L^-1.S^-1
Allotropes can be defined as different types of compounds made out of the same single element but in different chemical formulas and different arrangements. Isomers can be defined as the chemical compounds that have a similar molecular formula but with different structural formulae. Graphite and Diamond.
