Assertion (A) : If `30 mL` of `H_(2)` and `20 mL` of `O_(2)` react to form water, `5 mL` of `H_(2)` is left at the end of the reaction.
Reason (R ): `H_(2)` is the limiting reagent.

A

Statement 1 is true, statement 2 is true, statement 2 is a correct explanation for statement 1

B

Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 1

C

Statement 1 is true, statement 2 is false

D

Statement 1 is false, statement 2 is true

Text Solution

Verified by Experts

The correct Answer is:
D
Statement 1 is wrong, but Statement 2 is correct.
`underset(("30 mL 15 mL"),("reacted"))(H_(2)+1/2 O_(2)) rarr H_(2)O`
Volume of `O_(2)` left `=20-15=5 mL`
Statement 2 is correct, since `H_(2)` is completely consumed, and hence is the limiting reagent.
