The fission reaction must be possible.
The activation energy of a reaction is the minimum amount of energy required for a reaction to occur. It represents the energy barrier that must be overcome for the reaction to proceed. The value of activation energy varies depending on the specific reaction.
A reaction that emmits heat is called an exothermic reaction .
The reaction must change the chemical nature of reactants.
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
whoever asked this is a retard. combustion is a reaction between a fuel and oxygen in the air. during the reaction, the temperature around must be sufficiently high enough to keep up the heat of the combustion. whoever asked this is a retard. combustion is a reaction between a fuel and oxygen in the air. during the reaction, the temperature around must be sufficiently high enough to keep up the heat of the combustion.
No, it is not true that the activation energy of an endothermic reaction must be greater than the required ΔH. The activation energy (Ea) is the energy barrier that must be overcome for a reaction to proceed, while ΔH represents the overall change in enthalpy during the reaction. In an endothermic reaction, Ea can be less than, equal to, or greater than ΔH; it depends on the specific reaction mechanism and energy landscape.
For a reaction to be feasible for titration, it must be a quantitative reaction, meaning it goes to completion with a known stoichiometry. The reaction must also be fast enough to proceed to completion within a reasonable time frame. Additionally, the reaction should have a distinct endpoint to indicate completion.
You must have your own reaction.
Andrew Johnson
Oxygen gas must be present for a combustion reaction to occur.
To get an allergic reaction you must be allergic to this food. If it enters the mouth,eyes, nose or any place that has an opening you will get the reaction.
