The rise in temperature is affected by the amount of anhydrous sodium carbohydrate added to 20ml of water
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
This is an endothermic reaction.
They can all affect the rate of a chemical reaction.
Changing temperature, density and pressure occur when a chemical reaction.
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
He was investigating about an element and a chemical reaction happened that caused him to discover it.
Raising the temperature makes chemical reactions faster.
The reaction rate of a chemical reaction is dependent on temperature.
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Because a chemical reaction has different sign's. And heat is one. But if the temperature is dropping then it is not going through a chemical change.
yes.
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
This is an endothermic reaction.
