Question

Order of a reaction can be:

• A. Fractional
• B. Zero
• C. Integer
• D. All the above

Answer 1

The correct option is D

All the above

The order of a reaction is not necessarily an integer. It could be any of the following:

Zero: A zero-order indicates that the concentration of that species does not affect the rate of a reaction
Negative integer: A negative order indicates that the concentration of that species inversely affects the rate of a reaction
Positive integer: A positive order indicates that the concentration of that species directly affects the rate of a reaction
Fractional: Fractional orders, both positive and negative, represent more intricate relationships between concentrations and rate in more complex reactions.
