Question

Which of these is not a factor influencing the rate of a chemical reaction?
A: the concentration of reactants
B: the surface area of the reactants
C: the presence of a catalyst
D: the volume of the container in which the reaction occurs

Answer 1

Catalyst lowers activation energy so the rate of the reaction increases but there's no effect on the equilibrium.

Answer 2

I personally think it is B or D....?

Answer 3

Think about this



the uncatalyzed reaction wont happen as quickly because the reactants need to collide with sufficient energy to overcome the activation energy barrier. but if you lower the activation energy, the reaction happens faster. so the rate goes up.

increasing concentration and surface area, will also increase your rate of reaction. remember higher concentration implies more collisions and more collisions means that the chance particles collide properly to form products goes up.

Changing the volume would affect the equilibrium more, though I think it's possible it may also affect reaction rate too but it would mostly affect equilibrium. that's why I think it's D.

Answer 4

is this clear to you?
