Which change will increase the rate of an endothermic reaction in the forward direction?
Increasing the temperature will enhance the rate of an endothermic reaction in the forward direction. Since endothermic reactions absorb heat, providing additional heat energy will shift the equilibrium toward the products, thereby increasing the reaction rate. Additionally, increasing the concentration of reactants or using a catalyst can also help speed up the reaction.
Is cleaning silver an endothermic or exothermic reaction?
Cleaning silver typically involves a chemical reaction that can be classified as endothermic. For example, when using silver polish or a chemical solution like baking soda and aluminum foil in warm water, the reaction absorbs heat from the surroundings, resulting in a drop in temperature. Thus, the process of cleaning silver requires energy input, making it endothermic.
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
How do you classify a chemical reaction?
Chemical reactions can be classified based on the type of reaction (e.g., synthesis, decomposition, single replacement, double replacement) or the energy changes involved (e.g., exothermic, endothermic). Classification helps in understanding the underlying principles and predicting the products of reactions.
What reaction produces thermal energy?
The most common reaction producing heat is burning, in which fuel is combined with oxygen from the atmosphere to produce heat which is a form of thermal energy. The problem of using the heat in the most efficient way possible in engines leads to the science of Thermodynamics, a branch of physics.
What is a sentence using the word endothermic?
(An endothermic process is one that absorbs heat.)"An endothermic reaction just took place between the water and the chemical.""Boiling water is an endothermic process that adds energy to the water molecules."
What kind of reaction is photosynthesis?
Photosynthesis is a chemical reaction that converts carbon dioxide and water into glucose and oxygen using sunlight as an energy source. It is a complex process that occurs in plants, algae, and some bacteria.
What are two chemical reactions that require energy in order to occur?
Photosynthesis: The reaction where carbon dioxide and water are converted into glucose and oxygen by plants using sunlight. Endothermic reactions: Reactions that involve the absorption of heat energy from the surroundings, such as the decomposition of calcium carbonate to form calcium oxide and carbon dioxide.

Difference between endothermic and exothermic?
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
What is a sentence using endothermic and exothermic?
Plants are endothermic because they use photosynthesis as their means of obtaining energy and endothermic means energy obtaining. A candle flame would be considered exothermic because it releases heat.

Thus, the process of cleaning silver requires energy input, making it endothermic.
How can one determine if a reaction is endothermic or exothermic without relying on enthalpy values?
One way to determine if a reaction is endothermic or exothermic without using enthalpy values is by observing the temperature change during the reaction. If the temperature increases, the reaction is likely exothermic, releasing heat. If the temperature decreases, the reaction is likely endothermic, absorbing heat.

Do self heating cans warm up their contents using an exothermic or endothermic reaction?
Self-heating cans warm up their contents using an exothermic reaction. This reaction typically involves mixing water with quicklime (calcium oxide), which generates heat as it reacts to form calcium hydroxide.
