Question

The chemical reaction occurs during photosynthesis is _____________.
a) CO2 is reduced and water is oxidized
b) water is reduced and CO2is oxidized
c) both CO2 and water are oxidized
d) both CO2 and water are produced

Answer 1

photosynthesis equation is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2 so here option c is correct becoz in both CO2 and H2O the oxygen is having -2 oxidation state bt when 6 mole O2 is formed then it is in 0 oxidation state. that's why c is correct

Answer 2

a)CO2 is reduced and water is oxidized.
