WebHill reaction: ( hil ), that portion of the photosynthesis reaction that involves the photolysis of water and the liberation of oxygen and does not include carbon dioxide fixation. It involves … WebThe reaction is to be performed as follows: 1. Place a test tube rack 25 cm from the light source with a “heat-sink” in between. Since the rate of the Hill reaction is affected by temperature, a container of water will be placed between the light source and the reaction tubes. The water acts as a sink for the heat and
