How will you judge whether a chemical reaction is exothermic or endothermic in nature?
A chemical reaction is exothermic if it releases heat to its surroundings, causing an increase in temperature. On the other hand, a reaction is endothermic if it absorbs heat from its surroundings, resulting in a decrease in temperature. This can be determined by measuring the temperature change during the reaction or by analyzing the enthalpy change of the reaction.
Why does a change in body temperature indicate that a chemical reaction may have occurred?
A change in body temperature can indicate a chemical reaction because most chemical reactions involve the absorption or release of energy in the form of heat. If the reaction absorbs heat from the surroundings, it can cause a decrease in temperature, while if it releases heat, it can cause an increase in temperature. Monitoring changes in body temperature helps to detect and analyze chemical reactions.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.

What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
What is the impact of a change in temperature on the delta S of surroundings in a chemical reaction?
A change in temperature can affect the entropy change (delta S) of the surroundings in a chemical reaction. When the temperature increases, the surroundings absorb more heat energy, leading to an increase in entropy. Conversely, a decrease in temperature results in a decrease in entropy of the surroundings.
Does the change of temperature will slow or faster the chemical reaction?
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.
Why does the temperature increase and decrease during neutralization?
During neutralization, an acid and a base react to form water and a salt. This reaction is usually exothermic, releasing heat and causing the temperature to increase. As the reaction progresses and reaches completion, the temperature may then decrease as the system returns to equilibrium.
What is the relationship between an enzyme temperature and the chemical reaction in which the enzyme is invoved?
Rate increase with temperature up to 40 celcius.But it decrease to 60 celcius and stops after.
How will you judge whether a chemical reaction is exothermic or endothermic in nature?
A chemical reaction is exothermic if it releases heat to its surroundings, causing an increase in temperature. On the other hand, a reaction is endothermic if it absorbs heat from its surroundings, resulting in a decrease in temperature. This can be determined by measuring the temperature change during the reaction or by analyzing the enthalpy change of the reaction.
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.
How change will decrease the number of effective collisions during a chemical reaction?
An increase in temperature will lead to an increase in the kinetic energy of molecules, causing them to move faster and collide more frequently. This will result in more effective collisions during a chemical reaction.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
Enzymes decrease the activation energy of a chemical reaction. They do this by providing an alternative pathway with a lower activation energy that allows the reaction to proceed more rapidly.
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.
Why does a change in body temperature indicate that a chemical reaction may have occurred?
A change in body temperature can indicate a chemical reaction because most chemical reactions involve the absorption or release of energy in the form of heat. If the reaction absorbs heat from the surroundings, it can cause a decrease in temperature, while if it releases heat, it can cause an increase in temperature. Monitoring changes in body temperature helps to detect and analyze chemical reactions.
