Consider the following reaction: 2NO(g)+O2(g)⇌2NO2(g) The data
in the table show the equilibrium constant for this reaction
measured at several different temperatures.
Temperatures: Kp:
170K 3.8*10^-3
180K 0.34
190K 18.4
200K 681
Part A Use the data to find ΔH∘rxn and ΔS∘rxn for the
reaction.
i found ΔH∘rxn = 114 kJ but i dont know how to
get ΔS∘rxn. please help and show work
Answer
Draw a graph between #media_tag_0$on the x-axis, and @media_tag_1$ on the y-axis. You will get a straight line. Find the equation to calculate the straight line. Find the slope of the straightline and the intercept.
The straight line is obtained by using the equation
. The slope of the straight line equals
.
is the relationship between equilibrium constants and standard Gibbs energy.
is the relationship between standard Gibbs energy change, standard equilibrium change, and standard Enthalpy Change.
is constant gas temperature and is temperature in Kelvin scale.
From the given values of temperature (
values, as follows:
on the x-axis, and HTML1$on the y-axis looks like this:
The slope of the straightline is
and the intercept is
.
Ans:
has a value of , and HTMLmedia_tag_24$ has a value of
.
