The reaction represents the formation of methane (CH₄) from carbon (C) and hydrogen gas (H₂) with a negative enthalpy change of -74.9 kJ, indicating it is exothermic. This means that the reaction releases energy, typically in the form of heat, to the surroundings. The profile suggests that the reactants (C and H₂) have higher energy than the products (CH₄), resulting in a stable product formation. The energy released can be utilized in various applications, including energy production and fuel synthesis.

What is described in the following equation 2h2g plus o2g 2h20i?
The equation (2 \text{H}_2\text{g} + \text{O}_2\text{g} \rightarrow 2 \text{H}2\text{O}{\text{i}}) describes the chemical reaction of hydrogen gas ((H_2)) reacting with oxygen gas ((O_2)) to form liquid water ((H_2O)). This is a combustion reaction where two molecules of hydrogen gas combine with one molecule of oxygen gas to produce two molecules of water. The reaction is exothermic, releasing energy in the form of heat.
What reaction is 2h2g o2g --- 2h2og?
The reaction ( 2 \text{H}_2(g) + \text{O}_2(g) \rightarrow 2 \text{H}_2\text{O}(g) ) represents the combustion of hydrogen gas in the presence of oxygen gas to produce water vapor. This is an exothermic reaction, meaning it releases energy, typically in the form of heat and light. It is also a redox reaction, where hydrogen is oxidized and oxygen is reduced.
Which reaction would cause a increase in entropy?
CH4g + H2Og COg + 2H2g
