Alab experiment to determine the rate of atp production and its use in plants is conducted. in the lab, twenty circles cut from plant leaves are placed in a container of water with a light source, which allows photosynthesis to occur. when the rate of atp production exceeds the atp use, oxygen is given off by the plant cells, causing the leaf circles to float.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
