STATEMENT-1: Phenol is more reactive than benzene towards electrophilic substitution. 
STATEMENT-2: In the case of Phenol, the intermediate carbocation is more resonance stabilized.

By means of resonance, the phenol's hydroxyl group raises the benzene ring's electron density.
In the orthogonal and paragonal positions, the electron density is higher.
Increased electrophilic aromatic substitution reactivity is seen.
Additionally stabilised by resonance is the intermediate carbocation.
In light of this, phenol is more reactive than benzene toward electrophilic processes.

Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1.
