Answer:
How to Formulate an Effective Research Hypothesis
State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
Try to write the hypothesis as an if-then statement. ...
Define the variables.
Explanation:
Answer: The volume is 57.52 mL if the temperature if raised to 343K.
Explanation:
Given: 
= 27 mL, 
= 161 K
= ?, 
= 343 K
According to Charles law, at constant pressure the volume of an ideal gas is directly proportional to temperature.
Formula used is as follows.
Thus, we can conclude that volume is 57.52 mL if the temperature if raised to 343K.

There are two equations of Gibb's free energy, ΔG°:
ΔG° = ΔH° - TΔS°
ΔG° = -RTlnK
Let's use the first equation. Since ΔS° is negligible, it is equal to 0. Therefore, ΔG° = ΔH° = 7.11 kJ/mol. We use this value to the second equation.
7.11 kJ/mol = -(8.314 J/mol·K)*(1 kJ/1000 J)*(25 + 273 K)*(lnK)
lnK = -2.8697
K = 0.05671
Therefore, the equilibrium constant is equal to 0.05671.
