Catalysts permit reactions to proceed along a ___________energy path.
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
Increasing the concentration of the reactants will slow down the reaction.
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
The rate of a chemical reaction is NOT affected by which of the following:
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
A ______________ is a substance that increases the rate of a reaction without being used up during the reaction.
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
Products will form faster if____________
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
Usually lowering the temperature will slow down a reaction.
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
Increasing the temperature will increase the kinetic energy of particles, therefore increasing the collisions between particles.
true
catalyst
concentration of the reactants are increased.
lower
false
all of these affect reaction rate
larger
true
The ___________ the surface area of the reactants, the faster the reaction rate.
true
catalyst
concentration of the reactants are increased.
