Question

the equation C+O2------> CO2 delta H= -408Kj represents
1) Endothermic
2) Exothermic
3) Reversible ​

Answer 1

Answer:

Given:

A chemical equation has been provided.

C + O2 => CO2

To find :

Whether the reaction is Exothermic or endothermic or reversible ?

Concept:

Whenever the enthalpy status of a reaction is negative, we can say that the system released energy to the surroundings. This type of reaction is called Exothermic Reactions.

Here,

∆H = negative, hence the reaction is Negative.

We can also see that the reaction uses the following sign:

" --------> "

This sign means that the reaction is irreversible.

So the correct answer is option 2)

Answer 2

Answer:

endothermic I hope it's helpful and correct
