Chemistry Graphs: Reaction Rates
Use the given
to answer the following questions.
If the general
for a reaction is written as
, then the
of the reaction can be expressed as
is negative. Explain how this is reflected on the graph.
According to the graph, are the reactants disappearing at a constant rate?
According to collision theory, molecules must collide in order to react. Where on the
rate of reaction
is greatest? Where is it slowest?
The plot of the
of the products versus time is a mirror
plot. What does this imply about the stoichiometry of the reaction?
shows that the
decreases by half in 50 seconds. What is the
after 50 seconds? If the
again decreases by half, what is the
after 100 seconds? After 150 seconds?
What is the sum of the
at any given time?
