Problem

You may want to reference (Pages 191 - 192) Section 5.8 while completing this problem.

The sun supplies about 1.1 kilowatt(s) of energy for each square meter of surface area (1.1 kW/m2, where a watt = 1 J/s). Plants produce the equivalent of about 0.21 g of sucrose (C12H22O11) per hour per square meter.

Assuming that the sucrose is produced as follows, calculate the percentage of sunlight used to produce sucrose.

12 CO2(g) + 11 H2O(l) → C12H22O11 + 12O2(g), ΔH = 5645kJ
