0.01M NaHCO3: At a light intensity of 4 the rate is 0.06 but this rises to 0.6 when the light intensity is brought up to 400. The curve is very shallow and levels off towards a light intensity of 350 – 400. 0.02M NaHCO3: The amount of NaHCO3 is double that of the 0.01M NaHCO3 experiment. The rate also finishes off twice that of the 0.01M experiment. This would suggest that there was a directly proportional relationship between the amount of NaHCO3 and the rate of reaction. 0.05M NaHCO3:
