What happens when sulfonic acid reacts with methanol?
Sulfonic acids can react with low molecular weight alcohols such as methanol, ethanol, or isopropanol through different mechanisms to form the corresponding sulphonateesters.

sulfonic acid is not a substance, but a class of compounds where one of the OH groups has been replaced by an organic moiety (R) forming RSO2(OH). Methanol (MeOH)can displace water to form the affiliated methyll ester: RSO2(OMe).

Out of this two methanol is the strongest acid, because after the loss of acidic proton i.e. H+ the corresponding anion formed by methanol is stabilized by the electronegative oxygen atom.

when methanol is heated with conc. H₂SO₄,methyl hydrogen sulphate is obtained in first step.This on further treatment with another mole of methanol gives methoxy methane along with H₂SO₄. This reaction is known as continuous etherification reaction.

CH₃-OH + H₂SO₄—-> CH₃-OSO₃H + H₂O
CH₃-OSO₃H + CH₃-OH—> CH₃-O-CH₃ + H₂SO₄

General Form: Alcohol + carboxylic acid is reversible with ester and water
Specifically: [math]C_2H_5OH + HCOOH <-> C_2H_5OOCH + H_2O[/math]
Name of organic product: Ethyl Methanoate

I have a feeling your Rs are in the wrong places! I.e. it should go CH2-R1-COOH
etc.
And then it's just a simple esterification process i.e. CH2-R1-COOH +MeOH --> CH2-R1-COOMe
