Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a limiting factor?
A
The factor which increases the rate of a reaction
B
The factor that limits the reaction rate
C
The factor that limits the rate at which an enzyme is destroyed
Explanation: 

Detailed explanation-1: -Within stoichiometry, limiting factors are the reactants or reagents within a chemical reaction that are consumed by the reaction before other reactants. The limiting factor is the reactant or reagent that has the lowest supply regarding its needed ratio compared to other reactants within the system.

Detailed explanation-2: -Limiting factors affect the rate of a reaction. A limiting factor is a condition, that when in shortage, slows down the rate of a reaction. Light intensity, carbon dioxide concentration and temperature are limiting factors for the rate of photosynthesis.

Detailed explanation-3: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-4: -What is the Blackman’s Law of Limiting Factors? If a chemical process is affected by more than one factor, then 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.

Detailed explanation-5: -The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
