1. The problem statement, all variables and given/known data 6CO2 + 6 H2O → C6H12O6 + 6 O2 Now suppose the above reaction is allowed to proceed in both directions, and has reached equilibrium. How would increasing the concentration of oxygen change the concentrations of carbon dioxide and sugar? 2. Relevant equations 3. The attempt at a solution Would the concentration of oxygen in both the sugar and carbon dioxide increase since oxygen is essential to both of them? I have trouble with equilibrium and problems like this, any help or hints are greatly appreciated, thanks!
