Equilibrium Reactions: A
Comprehensive Guide to Chemical
Balance
Standard conditions are defined as _______ K temperature and ________
atmosphere pressure - 298, 1
When a reaction results in almost complete conversion of reactants to products,
chemists say that the reaction goes to _________. - completion
Most reactions do not go to completion; they appear to ______ (condition). The
reason is that these reactions are reversible. - stop
A ________ is one that can occur in both the forward ad the reverse directions. -
reversible reaction
Chemists can combine two reversible equations into a single equation that uses a
__________ symbol to show that both reactions occur. - double arrow
When you read a reversible equation, the products in the forward ________ are on
the ________ (right/left) - reaction, right
In the reverse reaction, the reactants are on the ________ (right/left). - right
Recall from chapter 17 that the rate of reaction focuses on the change in _______ of
the reactants. - concentration
Constancy doesn't mean that the reactions have ______ but that a state of
equilibrium has been established. - stopped
As the reaction proceeds, the rate of the forward reaction continues to decrease and
the rate of the reverse reaction continues to increase until the two rates are
_________. - equal
In figure 1, ammonia is being produces as fast as it is being decomposed, so the
concentrations of nitrogen, hydrogen, and ammonia remain ____________. -
constant
___________ __________ is a state in which the forward and reverse reactions
balance each other because they take place at equal rates. - Chemical equilibrium
At equilibrium, the concentrations of reactants and products are constant. However,
that doesn't mean that the amounts of concentrations of reactants and products are
________. - equal
You have learned that some chemical systems have little tendency to react and
others go readily to completion. In between these two extremes are the majority of
