Why does the reaction involve water and why isn't H2SO4 directly involved?

The title does not mention hydrolysis.

For hydrolysis you do not use concentrated acid.

Dilute acid and heat hydrolyses the ester to the alcohol and carboxylic acid ... The hydrogen ions catalyse the reaction.

Can you write the equation for the formation of the ester from the acid and the alcohol.

Can you reverse the (equilibrium) reaction?

Why would you add H2SO4 for the forward reaction?

Catalysts lower the activation energy (sorry) in both directions.

Hi all, found this forum as i need help with my A level chemistry homework, My teacher has set a range of questions for us to answer, in less we went over hydrolysis with esters which i am find with and now i have homework on this apparently but I am confused from what i just read, my homework is entitled 'carboxylic acid and esters' now i am stuck on these questions:

1. write equations for the following reactions:
a. sodium methanoate with hydrochloric acid
b. sodium ethanoate with sulphuric acid
c. 2-methylpropanoic acid with sodium carbonate
2.
a. ethyl methanoate with concentrated h2so4
b. methyl propanoate with NaOH

Bruh just type it into Google, how dumb are you ffs

I think I have the same HW and am stuck on question 2a on your list;
The other ones I think I've done correctly, I will write below:

1.a. Sodium methanoate + HCl --> Methanoic acid + Sodium chloride
HCOONa + HCl --> HCOOH + NaCl

1.b. Sodium ethanoate + H2SO4 --> Ethanoic acid + Sodium sulphate
2CH3COONa + H2SO4 --> 2CH3COOH + Na2SO4

1.c. 2-methylpropanoic acid + Sodium carbonate --> Sodium 2-methylpropanoate + Water + Carbon dioxide
2CH3CH(CH3)COOH + Na2CO3 --> 2CH3CH(CH3)COONa + H2O + CO2

2.b. Methyl propanoate + NaOH --> Sodium propanoate + Methanol
CH3CH2COOCH3 + NaOH --> CH3CH2COONa + CH3OH
