The sun supplies energy at a rate of about 10 kilowatt per square meter of surface area (1 watt = 1 y/s). The plants in an agricultural field produce the equivalent of 18.2 kg
sucrose (C12H22011) per hour per hectare (1 hectare = 10.000 m?). Assume that sucrose is produced by the reaction
12 CO2(8) + 11 H20 - C12H22011(s) 12 (8) AH = 5640 kJ
calculate the percentage of sunlight used to produce the sucrose-that is determine the efficiency of photosynthesis.
The reaction
SO3(8) + H2001) --- H250 (aq)
