The decimal reduction time in organic chemistry reactions refers to the amount of time it takes to achieve which of the following?
A
Reduce the concentration of a reactant by 90%
B
Double the concentration of a product
C
Increase the reaction rate by 10%
D
Reduce the concentration of a reactant by 50%
Verified step by step guidance1
Understand the concept of 'decimal reduction time' (D-value) in the context of chemical reactions. It is a term often used in kinetics to describe the time required to reduce the concentration of a reactant by a specific percentage.
Recognize that the D-value specifically refers to the time needed to reduce the concentration of a reactant by 90%. This is a key concept in reaction kinetics, particularly in processes like sterilization and degradation.
Consider the options provided in the problem: reducing the concentration of a reactant by 90%, doubling the concentration of a product, increasing the reaction rate by 10%, and reducing the concentration of a reactant by 50%.
Identify that the correct interpretation of 'decimal reduction time' aligns with reducing the concentration of a reactant by 90%. This is because the term 'decimal' implies a reduction by one order of magnitude, which corresponds to a 90% reduction.
Conclude that the correct answer is the option stating 'Reduce the concentration of a reactant by 90%', as this matches the definition of decimal reduction time in organic chemistry.
