For each statement below, write true or false _____________1. When the temperature of the reactants increases the heat within that if transferred heat is transferred within the particles of the substance thereby increasing the amount of its energy. ____________2. When you increase the surface area of the reactant, more particles are exposed to other reactants thereby increasing the frequency of the collision. ____________3. Whenever there’s an increase in concentration or pressure, the amount of energy per unit volume also increases and would mean an increase in the collision of the particles. ____________4. They speed up the reaction, but they are not consumed in the process of the reaction. ____________5. Increasing the temperature will increase the kinetic energy of particles, therefore increasing the collisions between particles.

4. • RECALL: IN OUR DAILY LIFE WE PERFORM VARIOUS ACTIVITIES THAT EXHIBITS CHANGE, AS SIMPLE
AS DISSOLVING COFFEE AND SUGAR IN A GLASS OF WATER OR OUR FAVORITE POWDERED JUICE
DRINK, COOKING RICE AND FRIED EGGS BUT THE QUESTION IS WHAT AFFECT THE CHANGE IN THE
CHEMICAL REACTION IN SUCH AWAY THAT IT RESULT TO AN EDIBLE OR DRINKABLE PRODUCT?
• WE LEARNED FROM UNDERSTANDING THE BASIC NATURE OF REACTION TO HEAT AND THIS GIVE US
AN OPPORTUNITY TO SEARCH FOR MORE AND TO STIMULATE ONE’S MIND TO LOOK FOR ANSWERS
ON HOW, WHAT AND WHY THINGS RESULTED THE WAY THEY DO.
ENGAGEMENT

5. •DETERMINE HOW VARIOUS FACTORS
INFLUENCE THE RATE OF REACTION.
•DISCUSS THE CONCEPT OF ACTIVATION
ENERGY AND HOW IT IS RELATED TO
REACTION RATES
OBJECTIVE
:

6. WHAT’S IN
FOR EACH STATEMENT BELOW, WRITE TRUE OR FALSE
_____________1. WHEN THE TEMPERATURE OF THE REACTANTS INCREASES THE HEAT
WITHIN THAT IF TRANSFERRED HEAT IS TRANSFERRED WITHIN THE PARTICLES OF THE
SUBSTANCE THEREBY INCREASING THE AMOUNT OF ITS ENERGY.
____________2. WHEN YOU INCREASE THE SURFACE AREA OF THE REACTANT, MORE
PARTICLES ARE EXPOSED TO OTHER REACTANTS THEREBY INCREASING THE FREQUENCY OF
THE COLLISION.
____________3. WHENEVER THERE’S AN INCREASE IN CONCENTRATION OR PRESSURE, THE
AMOUNT OF ENERGY PER UNIT VOLUME ALSO INCREASES AND WOULD MEAN AN INCREASE
IN THE COLLISION OF THE PARTICLES.
____________4. THEY SPEED UP THE REACTION, BUT THEY ARE NOT CONSUMED IN THE
PROCESS OF THE REACTION.
____________5. INCREASING THE TEMPERATURE WILL INCREASE THE KINETIC ENERGY OF
PARTICLES, THEREFORE INCREASING THE COLLISIONS BETWEEN PARTICLES.
