Which of the following describes a system that cannot be thermodynamically favored?
a.) δs is negative and δh is positive
b.) δs is positive and δh is positive
c.) δs is negative and δh is negative
d.) δs is positive and δh is negative

d) ΔS is positive and ΔH is negative

Explanation:

According to Gibb's equation:

= Gibbs free energy  

= enthalpy change

= entropy change  

T = temperature in Kelvin

= +ve, reaction is non spontaneous

= -ve, reaction is spontaneous

= 0, reaction is in equilibrium

a)  ΔS is negative and ΔH is positive

Reaction is spontaneous at all temperatures.

b) ΔS is positive and ΔH is positive

Reaction is spontaneous at high temperatures.

c) ΔS is negative and ΔH is negative

Reaction is spontaneous at low temperatures.

d) ΔS is positive and ΔH is negative

Reaction is non spontaneous or thermodynamically unfavored at all temperatures.

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
