Self-test 4.7 (a) Calculate the standard reaction entropy for N2(g) + 3 H2(g)2 NH3 (g) at 25 °C. (b) What is the change in en

Answer 1

Answer #1

a)

Standary entopy of No, tz & NH3 are AS ₂ = 191.5 /mork AS 4 = 130.6J/molk ASN = 192.5 J/molk Standard reaction enbopy , As -

b)

b) We have to convest the equation such that 2 mol of the rearts. - anty Ñ + 3t Multiply both sides by 2/3, we get 2 N2 + 2H2

Using standard entropy values of N_2,H₂ and NH₃ from internet the calculations are done.
