Answer:
Exothermic reaction
Explanation:
The freezing of n-octane is an exothermic reaction.
An exothermic reaction is a type of reaction in which energy usually in the form of heat is released to the environment. In an exothermic reaction, the reactants are at a higher energy level compared to the product. Hence heat energy is usually released.
Now, freezing is a change in state from the liquid state to the solid state , for example, the turning of water to ice block.
In freezing, energy is released and hence, thus it is an exothermic reaction
The freezing of n-octane is an exothermic process.
An exothermic reaction is a reaction in which heat is released to the environment inform of heat.
Exothermic reaction is also a reaction for which the overall standard enthalpy change ΔH⚬ is negative. Exothermic involve the replacement of weak bonds with stronger ones.
Therefore, The freezing of n-octane is an exothermic process because heat is lost or released to the environment.
