MATTER: PROPERTIES AND TRANSFORMATION: Rates Of Reaction
__ is the minimum amount of energy that reactant particles must possess before collisions between them will lead to a chemical reaction
Transition energy
Collision energy
Thermal energy
Activation energy
According to the collision theory?
Reactant particles must also possess a certain minimum amount of energy called the activation energy (E
A
) for a reaction to occur.
Chemical reactions occur due to collisions between reactant particles.
None is correct.
Chemical reactions occur due to collisions between reactant particles and reactant particles must also possess a certain minimum amount of energy called the activation energy (E
A
) for a reaction to occur.
Which graph shows: An increase in speed of a chemical reaction with an increase in temperature of the reacting particles
D
C
A
B
Example(s) of photochemical reactions include __
Photosynthesis
All are correct
The reaction between hydrogen and chlorine
The reaction between methane and chlorine
Select the correct statement concerning the effect of concentration on reaction rates.
An increase in the concentration of reactants increases the rate of a chemical reaction while a decrease in the concentration of reactants reduces the rate.
An increase in the concentration of reactants increases the frequency of collision between the particles, leading to an increase in the rate of reaction.
An increase in the concentration of reactants increases the number of reactant particles and brings them closer to each other.
All are correct
