Question

A 2 mole sample of F2(g) reacts with excess NaOH(aq) according to the equation above. If the reaction is repeated with excess NaOH(aq) but with 1 mole of F2(g), which of the following is correct?
Group of answer choices

The amount of OF2(g) produced is doubled.

The amount of OF2(g) produced is halved.

The amount of NaF(aq) produced remains the same.

The amount of NaF(aq) produced is doubled.

Answer 1

Answer:

The amount of NaF produced is doubled.

(d) is correct option.

Explanation:

Given that,

A 2 mole sample of F₂ reacts with excess NaOH according to the equation.

The balance equation is

$2F_{2}+2NaOH\Rightarrow 2NaF +H_{2}O+OF_{2}$

If the reaction is repeated with excess NaOH but with 1 mole of F₂

The balance equation is

$F_{2}+2NaOH\Rightarrow 2NaF +2OH$

Hence, The amount of NaF produced is doubled.

(d) is correct option.
