Suppose we redefine the standard state as P= 2 bar . Find the new standard ΔfG∘ values of the following substances.
a) HCl(g)
b) N2O(g)
c) H(g)

Respuesta :

We have that the new values of the following substances HCl(g), N2O(g), H(g) is that the remain the same as

dG=dH-TdS remains the same.

Standard ΔfG∘ values of substances.

Question Parameters:

s P= 2 bar

HCl(g)

N2O(g)

H(g)

Generally the equation for the Change in Heat energy  is mathematically given as

dG=dH-TdS

Where

dH=CpdT

Therefore, With no change in entalpy dH only changes  when there is a change in dT

dS=CpInT

With dS independent of pressure S is constant

Hence, dG=dH-TdS remains the same
