Question

4) Calculate deltaG
delta H = - 105 delta S = + 3585ylk
at
450k​

Answer 1

Explanation:

For higher accuracy, you can account for the temperature dependence of

Δ

H

0

and

Δ

S

0

by considering the

Δ

T

between the actual temperature of reaction in the standard temperature of the thermodynamic table you're using. For example, if your reaction is at 350K and your table is for 298K then for each reactant and product the enthalpy and entropy of formation is:

Δ

f

H

350

=

Δ

f

H

298

+

C

P

(

350

−

298

)

S

350

=

S

298

+

C

P

ln

(

350

298

)

Then calculate the

Δ

H

and

Δ

S

for the reaction and the rest of the procedure is unchanged.
