The Gibbs free energy ΔG for the vaporisation of 2-methylbutane, in KJ/mol is 8.24 KJ/mol

<h3>Data obtained from the question </h3>
  • Enthalpy change (ΔH) = 25. 22 KJ/mol
  • Change in entropy (ΔS) = 84.48 J/Kmol = 84.48 / 1000 = 8.448×10¯² KJ/Kmol
  • Temperature (T) = 201 K
  • Gibbs free energy (ΔG) =?

<h3>How to determine the Gibbs free energy </h3>

The Gibbs free energy for the reaction can be obtained as follow:

ΔG = ΔH – TΔS

ΔG = 25.22 – (201 × 8.448×10¯²)

ΔG = 25.22 – 169.8048

ΔG = 8.24 KJ/mol

Thus, the ΔG for the reaction is 8.24 KJ/mol

alexandr402 [8]
Yellow lines means that roads are merging and there's going to be traffic coming, so it's a warning to be cautious and to join the merged road. It's usually a warning to people that are going at a high speed in their vehicle. So merging majorly helps prevent an accident.

Which is an advantage to using nonrenewable resources?
11111nata11111 [884]
The answer is A. Its relative cheapness compared to its renewable counterparts is what allows nonrenewable resources to continue to dominate the market. Also, you can conclude this answer through elimination of the other three choices. Nonrenewable resources actually have a higher impact on the environment because of its contribution to greenhouse gas emissions. Also, it being used up rapidly and contributing to global warming are both true, but are disadvantages rather than advantages.
