What else can I help you with?
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
Is mixtures have constant temperature?
is mixtures have constant temperature Dissolving this in that may be exothermic or endothermic, depending on the this and that. Oh, yea, it's not a chemical reaction. At least in the 20th Century it wasn't a chemical reaction, but now that Pluto is not a planet, and now that the visual spectrum has 5 instead of 7 "colors" -- who knows.
What changes can be made to a chemical reaction to increase the rate constant"?
To increase the rate constant of a chemical reaction, you can change factors such as temperature, concentration of reactants, presence of a catalyst, and surface area of reactants. These changes can speed up the reaction by providing more energy and effective collisions between molecules.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
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.
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
How an increase in temperature change the rate constant of a chemical reaction?
An increase in temperature generally increases the rate constant of a chemical reaction due to more frequent and energetic collisions between molecules, leading to a higher probability of successful reactions. This is described by the Arrhenius equation, which states that the rate constant of a reaction increases exponentially with temperature.
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
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.

Why does a chemical change in temperature indicate that a chemical reaction may have occurred?
A change of temperature implies that some energy has been transfered or used. Since chemical reactions either require or release energy to occur, the environment may change temperature as the substances react.
What factors doesn't change the equilibrium constant of a reaction?
The equilibrium constant of a reaction is unaffected by changes in concentration, pressure, or volume, as these do not alter the intrinsic properties of the reaction at a given temperature. Additionally, the equilibrium constant remains constant regardless of the presence of catalysts, which only speed up the rate at which equilibrium is reached but do not change the position of equilibrium itself. However, the equilibrium constant is temperature-dependent; a change in temperature will alter its value.
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.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
