Yes, they can occur spontaneously. This can be explained by entropy (measure of randomness/dispersion in a chemical system).
For example;
NH4NO3(s) + aq --> NH4+(aq) + NO3-(aq).
The solid ammonium nitrate is converted to liquid ions. Therefore, the entropy increases, so the reaction can take place spontaneously.
What else can I help you with?
Any reaction that absorbs 150 kcal of energy can be classified as?
Endothermic. Any reaction that ABSORBS energy is classified as endothermic.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
What Defines an Endothermic Reaction?
An endothermic reaction need heat to begin.
If heat is required for a reaction to occur what type of reaction is it?
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
Definition of endothermic?
Endothermic reactions or processes absorb heat from their surroundings to proceed, causing a decrease in temperature of the surroundings. Energy is required for the reaction to occur, resulting in a decrease of the system's internal energy.
Any reaction that absorbs 150 kcal of energy can be classified as?
Endothermic. Any reaction that ABSORBS energy is classified as endothermic.
What is is endothermic?
if any reaction requires heat to proceed itself than the reaction is called endothermic reaction..
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
Is water gas reaction endothermic?
yes it is a endothermic reaction
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
Reaction that absorbs energy in the form of heat?
Endothermic reaction. In an endothermic reaction, energy is absorbed by the system from the surroundings in the form of heat, causing the surroundings to cool down.
How is sherbet an endothermic reaction?
Endothermic
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
What does endothermic reaction do?
There are two types of reactions, thermally. Endothermic and exothermic. An endothermic reaction absorbs heat and an exothermic reaction releases it.
What Defines an Endothermic Reaction?
An endothermic reaction need heat to begin.
What is an endotherms?
An endothermic reaction is any chemical reaction that absorbs heat from its environment. Here's a list of examples of endothermic reactions. You can use these when asked to cite an example or to get ideas to set up a demonstration of an endothermic reaction or process.
How are endothermic reaction different from exothermic reaction?
Exothermic reaction: with release of heat Endothermic reaction: with absorption of heat
