Question

When a collision occurs between two reactant particles that, between them, have the required minimum kinetic energy, or activation energy, a product does not always form. Which of the following reasons explains this?
a.low temperature
b.small surface area
c.unfavorable geometry
d.low concentration

Answer 1

c.unfavorable geometry

Answer 2

Answer:  C.  Unfavorable geometry

Explanation: When collision occurs between two reactants in order to make a reaction possible there are 3 factors which are responsible.

a) Orientation factor

b) Energy factor

c) rate of collision

Thus out of the given options, unfavorable geometry is the correct one as temperature and concentration as well as surface area will have very little effect on the reaction.

If the geometry of the reactant is not complementary then the reaction would not lead successfully.
