Question

1. Which of the following observations is incorrect about the order of a reaction?

1. Order of a reaction is always a whole number
2. The stoichiometric coefficient of the reactants doesn't affect the order
3 Order of reaction is the sum of power to express the rate of reaction to the concentration terms of the reactants.
4 Order can only be assessed experimentally​

Answer 1

Answer:

2nd one is the correct answer!!!

Answer 2

Explanation:

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced
