What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
The heat energy content of the reactants of an endothermic reaction compared with products is?
In an exothermic reaction the reactants release energy to the environment when they react - like coal burning. In an endothermic reaction the reactants need to absorb energy from their environment when they react, so the reaction feels cold in your hand, or else you have to heat it continually to make it react. The products would then be at a higher energy level than the reactant were. Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.
What is an endothermic reaction?
An endothermic reaction is one that absorbs heat from the surroundings.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.
What statement correctly describes an endothermic chemical reaction?
higher potential energy and delta h increases
Which reaction is the product higher in energy than the reaction?
Endothermic

An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.

Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
What is an endothermic reaction?
An endothermic reaction is one that absorbs heat from the surroundings.
If the temperature after a reaction is higher is the reaction endothermic or exothermic?
If the temperature rises, the reaction is EXOTHERMIC where the system (reaction) is giving off heat to the surroundings (water, beaker, test tube, etc.).
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
The products of an endothermic reaction are less chemically stable. They required an input of energy to create so naturally they are at a higher energy state.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.
What statement correctly describes an endothermic chemical reaction?

Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
