Consider these hypothetical chemicalreactions:
{\rm a \rightleftharpoons b}, \quad\delta g = 13.2 kj/mol
{\rm b \rightleftharpoons c}, \quad\delta g = -28.9 kj/mol
{\rm c \rightleftharpoons d},\quad \delta g = 5.80 kj/mol
what is the free energy, delta g, for the overall reaction, \rm a \rightleftharpoons d ?
express your answer numerically inkilojoules per mole.

The value of free enrage that is ΔG for the overall reaction is  36.3 kJ/mol.

Explanation:

...[1]

...[2]

...[3]

To find ΔG for reaction :

...[4]

By using Hess's law:

[1] - [2] - [3] = [4]

The value of free enrage that is ΔG for the overall reaction is  36.3 kJ/mol.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
