Question

When C2H4(g) reacts with H2O(g) to form CH3CH2OH(g) according to the following equation, energy is released into the surroundings. C2H4(g) H2O(g) CH3CH2OH(g) Is this reaction endothermic or exothermic

Answer 1

Exothermic

General Formulas and Concepts:

Chemistry

Thermodynamics

• Exothermic - releases heat as a product
• Endothermic - absorbs heat as a reactant

Step-by-step explanation:

We are given that the reaction takes place between C₂H₄ (g) and H₂O (g) to form CH₃CH₂OH (g) and is releasing heat.

This means that heat would be product as it is being released during the reaction.

Therefore, we have an exothermic reaction.
