Answer:

a) ΔG∘ > 0

b) K < 1

c) The electrochemical cell based on this reaction cannot accomplish work on its surroundings.

Explanation:

The Gibb's free energy, ΔG∘, is related to the potential of the cell, E∘ through

ΔG∘ = -nFE∘

where n = number of electrons being gained or lost in the electric cell

F = Amount of Faraday's electricity

a) If E∘ < 0, that is, negative,

ΔG∘ = positive (Since n and F cannot be negative)

That is, ΔG∘ > 0

b) Will the equilibrium constant for the reaction be larger or smaller than 1?

The Gibb's free energy is also related to the equilibrium constant through

ΔG∘ = - nRT In K

where n = number of moles = always positive

R = molar gas constant = always positive

T = absolute temperature in Kelvin = almost always positive too.

Recall that ΔG∘ > 0, that is positive too,

Hence,

- nRT In K = ΔG∘

In K = -(ΔG∘/nRT)

Since all of the quantities on the right hand side are positive parameters,

In K = a negative number

Meaning that K is less than 1.

The equilibrium constant is less than 1.

K < 1

c) Can an electrochemical cell based on this reaction accomplish work on its surroundings?

The Gibb's free energy determines spontaneity.

A process with a negative Gibb's free energy is said to be spontaneous and gives off the free energy as the process proceeds.

A process with a positive Gibb's free energy is said to be non-spontaneous. This one cannot give free energy (work) out to the environment.

For this question, the Gibb's free energy is positive, hence, the electrochemical cell based on this reaction cannot accomplish work on its surroundings.

Hope this Helps!!!

What is one effect of the Gulf Stream
skad [1K]

Answer:

This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.

Many metals react with acids to produce hydrogen gas. A certain reaction produces 32.6 L of hydrogen gas at STP. How many moles
morpeh [17]

Answer: 1.46moles

Explanation:

Applying PV= nRT

P= 1atm, V= 32.6L, R= 0.082, T = 273K

Substitute and simplify

1×32.6/(0.082×273)=n

n= 1.46moles
