I want to know how benzylpenicillin(Penicillin G) gets hydrolysed in acid medium and how the ring opening occurs.
I know that substitution with EWG on alpha position of acyl carbon increases stability to acid-catalyzed hydrolysis because nucleophilicity of amide side chain carbonyl decreases so it would not be attacked by acid but i dont get how hydrolysis occurs exactly step by step till ring opening happens.
Thank you.

You can find mechanism of acidic hydrolysis of amides in any university organic chemistry textbooks and on internet

but what is the effect of substitution at alpha acyl carbon on hydrolysis?and what is the role of acetamide in hydrolysis too?
