Problem

Photosynthesis is a redox reaction i.e.,

\text{XCO}_2 + \text{XH}_2\text{O} \xrightarrow[\text{Chlorophyll}]{\text{hv}} (\text{CH}_2\text{O})_n + \text{XO}_2

; which one is not correct about it: (1) carbon is reduced and oxygen is oxidised (2) it may be classified as intermolecular redox reaction (3)

\text{O}_2

released comes from

\text{H}_2\text{O}

(4) equivalent mass of

\text{CO}_2

is 11 and of

\text{H}_2\text{O}

is 4.5
