Answer:
-0.85KJ
Explanation:
Given N2(g) + H2(g) <--->2NH3(g)
Kp =[ P(NH3)]²/[P(H2)]³[P(N2)]
Where P is the pressure of the gas
P(H2)b= P(N2) = 125atm
P(NH3) = 200atm
Kp = 2²/(125)³(125)
Kp = 2.048 ×10^-6
∆G = -RTlnKp
R =0.008314 J/Kmol
T = 25 +273/= 298k
= 8.314 ×10^-3 × 298 × ln(2.048 ×10^-6)
= -0.008314 × 298 × (-13.099)
= 32.45KJ
∆G = ∆G° + RTlnKp
∆G = -33.3 + 32.45
∆G = -0.85KJ or -850J
The reactants are what is put into the reaction equation to get the product. In this case water and ammonia are put into the equation to get the product ammonium hydroxide.
The first choice is the correct answer:
Water and ammonia

30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
Answer:
Explanation:
for spontaneous reaction,
ΔG is negative
K>1
E > 0
cell A:
ΔG and EO suggests that reaction is spontaneous. But K is less than 1.
Hence K is wrong
cell B:
ΔG and EO suggests that reaction is non spontaneous .But K is greater than 1.
Hence K is wrong
cell C:
E and K suggest than reaction is non spontaneous but ΔG suggest that reaction is spontaneous.
Hence ΔG is wrong
