Answer 5

Negative catalyst

Question 6

energy contents of the
molecules are altered to favor effective
contacts to produce new products (e.g.,
platinum)

Answer 6

Adsorption

Question 7

State of a system in which the
rate of the forward reaction is
equal to the rate of the reverse
reaction.

Answer 7

Chemical Equilibrium

Question 8

Any chemical reaction, once
initiated, is the result of two
opposing reactions. Forward and reverse
reactions

Answer 8

REVERSIBLE REACTIONS

Question 9

Rate of a reaction is proportional
to the product of the
concentrations of each reactant

Answer 9

LAW OF MASS ACTION

Question 10

A change in one of the variables
that describe
a system at
equilibrium produces
a shift in the
position of the equilibrium that
counteracts the effect of this
change

Answer 10
