Rate increases and increases the frequency of

Rate of reaction is affected by some factors such as concentration of reactant.When the concentration of one or more reactants increase, the higher the number of particles in a unit per volume.The frequency of collisions between the particles increases and increases the frequency of effective collisions.Hence, the rate of reaction increases.Besides, the rate of reaction […]

Bioluminescence luciferin molecules. Some bioluminescent organisms do not

Bioluminescence is light produced by a chemical reaction within a living organism. Bioluminescence is a type of chemi-luminescence, which is simply chemical reaction where light is produced. Chemistry: The chemical reaction that results in bioluminescence requires two unique chemicals: luciferin, photo protein. Luciferin is the compound that actually produces light. In a chemical reaction, luciferin […]
