`2H_(2) O_(2) (l) rarr 2H_(2)o(l) + O_(2) (g)`
`100 mL` of `X` molar `H_(2)O_(2)` gives `3L` of `O_(2)` gas under the condition when 1 mole occupies `24 L`. The value of `X` is

A

`2.5`

B

`1`

C

`0.5`

D

`0.25`

Text Solution

Verified by Experts

The correct Answer is:
A
Mole of `O_(2)` formed `= (3)/(24) = (1)/(8)`
`:.` Mole of `H_(2)O_(2) = (1)/(8) xx 2 = (1)/(4)`
`:. 100 xx X = (1)/(4) xx 1000 :. X = 2.5`

2H_(2) O_(2) (l) rarr 2H_(2)o(l) + O_(2) (g) 100 mL of X molar H_(2)O_(2) gives 3L of O_(2) gas under the condition when 1 moe occupies 24 L . The value of X is

2H_(2)O_(2)(l) rarr 2H_(2)O(l) + O_(2)(g) 100 mL of 2.5 molar H_(2)O_(2) gives O_(2) gas under the condition when 1 mol occupies 24 L. The volume of O_(2) evolved in liters is:

F_(2)(g)+H_(2)O(l) to

For the process, H_(2)O(l) to H_(2)O(g)

Decomposition of H_(2)O_(2) is retarded by : 2H_(2)O_(2)(l) rarr 2H_(2)O(l)+O_(2)(g)

O_(3)(g)+I^(-)(aq)+H_(2)O(l) to

Hydrogen peroxide in aqueous solution decomposes on warming to give oxygen according to the equation 2H_(2)O_(2)(aq)rarr2H_(2)O(l)+O_(2)(g) under conditions where 1 mole of gas occupies 24 dm^(3) . 100cm^(3) of XM solution of H_(2)O_(2) produces 3 dm^(3) of O_(2) . Thus, X is :
