I tried question 3 with calculating the standard enthalpy change for photosynthesis but I don’t think I did it right because my answer doesn’t make sense to me.
1. Which element is OXIDIZED, and which is REDUCED, during photosynthesis? Ox ygen is oxidized. Carbon u reduced. 2. Based on what you know about photosynthesis, redox, and combustion reactions, do you expect process to TAKE ENERGY or RELEASE ENERGY? i expect the Proceu to take energy, that 3. Use Standard Heats of Formation (on your Equation Sheet) to calculate the Standard Enthalpy Change for the reaction in kJ (AHrxn), Show all equations and calculations with units to receive credit. CO2: -343.5 KJ/mal AHO=1273,3 k/rll need 0, -5349.1k3/m0 7331 UX) 4. Is this an ENDOTHERMIC or EXOTHERMIC reaction? How does this answer compare to your prediction from Question 2? This 73 an exothermz reaction. Thris the opposite of ny from Questron 2 becase exothernie restions relecre energy Predietion 5. List all the things needed for a plant to grow. Where does most of the mass of a tree come from? ld be two things from your list...
