How do you change the temperature of a reaction?
You can change the temperature of a reaction by heating or cooling the reaction vessel using a heat source or a cooling system. Increasing the temperature can speed up the reaction by providing more energy for the molecules to react, while decreasing the temperature can slow down the reaction by reducing the energy available for the reaction to occur.
What was the change in temperature for each reaction after 10 minutes?
To determine the change in temperature for each reaction after 10 minutes, you would measure the initial temperature before the reaction began and then the final temperature after 10 minutes. The change in temperature is calculated by subtracting the initial temperature from the final temperature. If you have specific reactions or temperatures in mind, please provide those details for a more tailored response.
What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
Is this true or false a change in temperature is always an indicator of a chemical reaction?
False. A change in temperature can indicate a chemical reaction, but it is not always the case. Temperature changes can also result from physical changes, such as phase transitions (e.g., melting or boiling). Therefore, while temperature change can be a sign of a chemical reaction, it is not a definitive indicator on its own.
What rough relationship can be infer between temperature and rate of reaction?
reaction rate doubles with every 10 K temperature change
What is the temperature of a starfish?
Since the starfish is a cold-blooded animal, its body temperature is the same temperature as the surrounding water it lives in. Each starfish's temperature varies.
What is the body temperature of a starfish?

Why is it important to observe temperature change when two chemical are mixed?
Observing temperature change when two chemicals are mixed can provide insight into whether a chemical reaction has occurred. An increase or decrease in temperature may indicate that the reaction is exothermic or endothermic, respectively. Monitoring temperature change can also help determine the reaction rate and the efficiency of the reaction.
How do you change the temperature of a reaction?
You can change the temperature of a reaction by heating or cooling the reaction vessel using a heat source or a cooling system. Increasing the temperature can speed up the reaction by providing more energy for the molecules to react, while decreasing the temperature can slow down the reaction by reducing the energy available for the reaction to occur.
How does the temperature change during an exothermic reaction?
During an exothermic reaction, the temperature increases because heat is released as a byproduct of the reaction.
What piece of information will tell you which way the equilibrium of a reaction will shift due to a change in temperature?
The sign of the enthalpy change (∆H) of the reaction will indicate the direction in which the equilibrium will shift with a change in temperature. If ∆H is negative (exothermic reaction), an increase in temperature will shift the equilibrium towards the reactants; if ∆H is positive (endothermic reaction), an increase in temperature will shift the equilibrium towards the products.
How can you change the speed of a reaction?
Temperature can change the speed of some reactions.

Why does a change in temperature indicate that a chemical reaction may occur?
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.
