Hydrogen Gas Reacts Rapidly with Oxygen Gas: Understanding the Correct Chemical Equation

Hydrogen gas (H2) is a highly flammable and reactive gas that can ignite rapidly in the presence of oxygen (O2). This reaction is often facilitated by a catalyst, which is a substance that speeds up the reaction without being consumed or altered in the process. In this article, we will explore the correct chemical equation that represents the reaction between hydrogen gas and oxygen gas in the presence of a platinum catalyst.

The Importance of Platinum as a Catalyst

Platinum is a highly effective catalyst for the reaction between hydrogen gas and oxygen gas. It is a noble metal that is resistant to corrosion and can withstand high temperatures, making it an ideal choice for this reaction. When platinum is present, it speeds up the reaction by providing a surface for the reactants to bind to, allowing them to react more quickly and efficiently.

So, which equation correctly represents the reaction between hydrogen gas and oxygen gas in the presence of a platinum catalyst? Let's examine the two options provided:

Option A: $H_2(g) + O_2(g) + Pt \rightarrow H_2(g) + O_2(g)$

This equation suggests that the platinum catalyst is a reactant that is consumed in the reaction, which is not the case. Platinum is a catalyst, not a reactant, and it is not consumed in the reaction.

Option B: $H_2(g) + O_2(g) \rightarrow 2H_2O(l)$

This equation suggests that the reaction between hydrogen gas and oxygen gas produces water (H2O) as a product. However, this is not the correct equation for the reaction in the presence of a platinum catalyst.

The Correct Equation

The correct equation for the reaction between hydrogen gas and oxygen gas in the presence of a platinum catalyst is:

$2H_2(g) + O_2(g) \rightarrow 2H_2O(l)$

This equation shows that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The platinum catalyst is not shown in the equation, as it is not a reactant and is not consumed in the reaction.

Understanding the Reaction Mechanism

The reaction between hydrogen gas and oxygen gas in the presence of a platinum catalyst is a complex process that involves several steps. The platinum catalyst provides a surface for the reactants to bind to, allowing them to react more quickly and efficiently. The reaction mechanism involves the following steps:

1. Adsorption: The hydrogen gas molecules adsorb onto the surface of the platinum catalyst.
2. Activation: The adsorbed hydrogen gas molecules are activated by the platinum catalyst, allowing them to react with the oxygen gas molecules.
3. Reaction: The activated hydrogen gas molecules react with the oxygen gas molecules to produce water.
4. Desorption: The water molecules are desorbed from the surface of the platinum catalyst.

In conclusion, the correct chemical equation for the reaction between hydrogen gas and oxygen gas in the presence of a platinum catalyst is $2H_2(g) + O_2(g) \rightarrow 2H_2O(l)$. This equation shows that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The platinum catalyst is not shown in the equation, as it is not a reactant and is not consumed in the reaction. Understanding the correct chemical equation and the reaction mechanism is essential for designing and operating systems that involve the reaction between hydrogen gas and oxygen gas.
