Question

H2 decomposed at room temperature to give oxygen and water 1 which speed of apparatus can be used to measure this reaction

ScanSolve AI Tutor · Accepted Answer

Assuming the reaction refers to the decomposition of hydrogen peroxide ( $H_2O_2$ ) into oxygen gas and water, as hydrogen gas ( $H_2$ ) does not decompose to give oxygen and water:

2\text{H}_2\text{O}_2(aq) \longrightarrow 2\text{H}_2\text{O}(l) + \text{O}_2(g)

This reaction produces oxygen gas. The speed of the reaction can be measured by monitoring the volume of oxygen gas produced over time.

Identify the product to be measured.
The reaction produces oxygen gas ( $O_2$ ).
Select apparatus suitable for measuring gas volume.
To measure the volume of gas produced, a gas syringe or an inverted measuring cylinder (or burette) over water can be used. These pieces of apparatus allow for the collection and quantification of the gas evolved from the reaction mixture over specific time intervals.

The apparatus that can be used to measure the speed of this reaction is a $\boxed{\text{gas syringe}}$ .
