Homework #44: Kinetics/Equilibrium Day 1-2

Front

What is the energy of the reactants in a chemical reaction?

Back

The energy of the reactants is the total energy present in the starting materials before the reaction occurs.

Front

What does a catalyst do in a chemical reaction?

Back

A catalyst provides an alternative pathway with lower activation energy, making the reaction happen faster.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the energy of the products in a chemical reaction?

Back

The energy of the products is the total energy present in the substances formed after the reaction.

Front

What does it mean if a reaction is exothermic?

Back

An exothermic reaction releases heat to the surroundings, causing an increase in temperature.

Front

What does it mean if a reaction is endothermic?

Back

An endothermic reaction absorbs heat from the surroundings, causing a decrease in temperature.

Front

What is a chemical reaction?

Back

A chemical reaction is a process where substances (reactants) change into new substances (products).

Front

What is potential energy in the context of a chemical reaction?

Back

Potential energy is the stored energy in the reactants and products due to their positions and arrangements.

Front

What is the difference between reactants and products?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed after the reaction.

Front

What does it mean for a reaction to be reversible?

Back

A reversible reaction can go in both directions, forming reactants and products back and forth.
