Question
Chapter 20, Problem 20.62QP
Interpretation Introduction
Interpretation:
The half-life years of Neptunium-237 has to be determined.
Concept introduction:
Half-life: The time taken for one-half of the nuclei in the sample to decay. The half-life of the sample is independent of the quantity of radioactive material and depends on the decay constant of the nuclide in the sample.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
N2 (g) + 3H2 (g) = 2NH3 (g) AG⁰ = -34. KJ
Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this
system:
?
rise
Under these conditions, will the pressure of N2 tend to rise or fall?
☐ x10
fall
Is it possible to reverse this tendency by adding H₂?
In other words, if you said the pressure of N2 will tend to rise, can that be
changed to a tendency to fall by adding H₂? Similarly, if you said the
pressure of N2 will tend to fall, can that be changed to a tendency to rise
by adding H₂?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of H₂ needed to reverse it.
Round your answer to 2 significant digits.
