Solution:

• Blackman’s Law - If a chemical process is affected by more than one factor, its rate will be determined by the factor which is nearest to its minimal value: it is the factor which directly affects the process if its quantity is changed.
• Except for plants in shade or in dense forests, light is rarely a limiting factor in nature.
