Answer:
Reducing agent - S
Explanation:
The equation for the reaction is given as;
K2Cr2O3 + H2O + S --> SO2 + KOH + Cr2O3
The balanced equation is given as:
2K2Cr2O7 + 2H2O + 3S → 3SO2 + 4KOH + 2Cr2O3
The reducing agent can be obtained by comparing the oxidation number of the elements. Increase in oxidation number signifies a reducing agent
K:
Reactant - 1
Product - 1
Cr
Reactant - +2
Product - +3
O
Reactant - -2
Product - -2
H
Reactant - +1
Product - +1
S
Reactant - O
Product - +4
S has an increase in oxidation number hence it is the reducing agent.
Although Cr has an increase in oxidation number, it occurs as a compound.
