Question

For a reaction $X + Y \rightarrow Z$, rate $\propto$ [X]. what is

(i) molecularity and (ii) order of reaction?

• A. (i) 2, (ii) 1
• B. (i) 2, (ii) 2
• C. (i) 1, (ii) 1
• D. (i) 1, (ii) 2

Answer 1

Answer: (A)

(i) 2, (ii) 1

Answer 2

$X + Y + Z$

Rate $\propto \lbrack X\rbrack$; hence order of reaction = 1

Molecularity of reaction = 2
