What are the units used to measure free energy in a chemical reaction?

The units used to measure free energy in a chemical reaction are typically kilojoules per mole (kJ/mol).


What is the catalytic efficiency equation used to measure the effectiveness of a catalyst in a chemical reaction?

The catalytic efficiency equation, also known as the turnover number, is calculated by dividing the rate of the reaction without a catalyst by the rate of the reaction with a catalyst. This ratio helps measure how effectively a catalyst speeds up a chemical reaction.


Which ways can be used to measure reaction rate?

It depends on the reaction. A hydrolysis reaction involving a color change can be measured spectrophotometrically using UV/Visible or Infrared spectroscopy. Gas Chromatography can also measure the appearance of products or disappearance of reactants versus time.


How do you calculate the initial rate of reaction in a chemical reaction?

To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.


How should a student use a thermometer to determine if a reaction is exothermic?

To determine if a reaction is exothermic, a student should use a thermometer to measure the temperature change during the reaction. If the temperature increases, it indicates that the reaction is exothermic, releasing heat.

How is a reaction rate measured experimentally?

There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.


What does enthalpy of reaction measure?

The amount of energy that is used or released as heat in a reaction.


What is the measure of how fast a reaction occurs?

The measure of how fast a reaction occurs is called the reaction rate. It is typically determined by how quickly the reactants are consumed or the products are formed over a specific period of time. The reaction rate can be influenced by factors such as temperature, concentration, and catalysts.


What is centrifugal force a measure of?

Centrifugal force is a measure of the opposite reaction of a centripetal force.


What are the units used to measure free energy in a chemical reaction?

When a balloon is blown up then it is let go air molecules rush out of the balloon and join the air molecules in the earth's atmosphere. What happens to the enthaply in the balloon?

When the air rushes out of the balloon, it releases heat energy, which results in a decrease in enthalpy within the balloon. This process is known as an exothermic reaction, where energy is released to the surroundings.


Is the rate of reaction a measure of how quickly reactants turn into elements?

No, the rate of reaction is a measure of how quickly reactants are consumed or products are formed in a chemical reaction. It represents the change in concentration of reactants or products per unit time. The reaction may or may not involve the formation of elemental substances.
