Question

STATEMENT-1 The order of reaction can have fractional value.
STATEMENT-2 For an elementary reaction, the partial orders are determined by the reaction stoichiometry.
Examine the statements carefully and mark the correct answer according to the instructions given below:


Your Answer
A
If both statements are TRUE and statement -2 is the correct explanation of statement-1
Correct Answer
B
If both the statements are TRUE but statement-2 is NOT the correct explanation of statement-1
Your Answer
C
If statement-1 is TRUE and statement-2 is FALSE
Your Answer
D
If statement-1 is FALSE and statement-2 is TRUE

Solution

The correct option is B If both the statements are TRUE but statement-2 is NOT the correct explanation of statement-1
Order of a reaction wrt a certain reactant is defined as the exponent of the concentration of that reactant in  the rate equation. It indicates the extent to which a species affects the rate of the reaction. It can be a whole number or a fraction.

Elementary reactions have order equal to the sum of stoichiometric coefficients for each reactant. It is easily ascertainable that the partial orders can be determined by the reaction stoichiometry.
