We’re asked to determine which of the given factors affect the rate of a chemical reaction between two gases.
Reaction rates are influenced by 4 factors:
1. Concentration: for a reaction to occur, molecules must collide.
Increasing the number of molecules in a container increases their collisions and thereby cause the rate to increase.
2. Surface area: the greater the surface area, the greater the chance for the reaction to occur and the faster the reaction can occur.
The surface area depends on the geometry or structure of the compound.
Consider the following factors:
I. Concentration of reactants.
II. Temperature of reactants.
III. Surface area of reactants.
The factors that affect the rate of a chemical reaction between two gases are
A. I and II only
B. I and III only
C. II and III only.
D. I, II, and III
