In an endothermic reaction, what can we do to increase the amount of product?
Reduce reactant
Reduce temperature
Increase temperature
Reduce volume
Which one is false for catalyst?
Catalyst will be used up in reaction
It can decrease the activation energy
Catalyst has contribution on chemical reaction
Catalyst can be in a different phase with reactants
What is the name of principle explaining the phenomenon happening in reversible reaction when changes are applied?
Le Blanc
Le Chatelier
L'Hospital
Born-Haber
2 SO2(g) + O2(g) <--> 2 SO3(g)
What will happen to the reaction if we increase the pressure?
It will produce more SO3
Nothing will happen
O2 will be produced
More SO2 will be produced
To increase the rate of reaction for solid object, which way can't be done?
Increase the concentration
Increase surface area
Increase temperature
Use catalyst
What is the name of the theory that can help us understand how some factors affect the rate of reaction?
Collision Theory
Theory of Uncertainty
Atomic Theory
Kinetic Particle Theory
CH4 + 2O2 --> CO2 + H2O
If 8g methane (CH4) is consumed on 0.1 second, what is the rate of reaction according to methane?
80 mol/s
80 g/s
8 mol/s
0.8 mL/s
Why does the rate of reaction increase when we used higher concentration reactants?
More particles can collide
More particles have high energy
The orientation can be manipulated
The activation energy decreases
Which one(s) has/have to occur in order for a chemical reaction to happen?
The reactants must collide
The orientation of collision must be accurate
The energy of reactants must surpass the activation energy
All of the options are correct
What happens to an exothermic reversible reaction when we give the reactants and products more heat?
Nothing will happen
The equilibrium becomes slower
The reaction is shifted towards reactant
The reaction will not reach equilibrium
