Question

For the reaction 2A(g)+B(g) → 2D(g) AU' - -10.5kJ and
AS = - 44.1Jk-1
Calculate AG0 for the reaction at 300K
A
0.164 kJ
B
0.236kJ
C
0.017 kJ
D
0.0019 kJ​

Answer 1

Answer:

For the reaction,

2SO

2

(g)+O

2

(g)⇌2SO

3

(g)

Given that, ΔG

o

=−690.9R,T=300K

From the formula, ΔG

o

=−RTlnK

−690.9R=−R×300×InK

or lnk=

300

690.9

=2.303

or =2303logK=2303

or K=10

1

=10

Unit of K=(atm)

Δn

=(atm)

2−3

=(atm)

−1

∴K=10atm

−1
