Question

What is S for the reaction N2(g) +O2(g) 2NO? Use G = 173.3 kJ at 303.0 K and H = 180.7 kJ. Use G = H – TS.

Answer 1

Answer:

Yes the below choice was right! I just got a 100 on the quiz

Explanation:

Answer 2

Given information :

G = 173.3 KJ

H = 180.7 KJ

T = 303.0 K

S = unknown (?)

By using the given formula : G = H - TS , we can calculate the value of 'S'

On rearranging the formula we get : S = $\frac{H-G}{T}$

Plug in the value of G , H and T in the above formula :

S = $\frac{(180.7 KJ - 173.3KJ)}{303.0K}$

S = 0.02442 $\frac{KJ}{K}$
