Answer:
K(79°C) = 1.906 E7 s-1
Explanation:
Arrhenius eq:
∴ A = 5.0 E9 s-1
∴ Ea = 16.3 KJ/mol
∴ R = 8.314 E-3 KJ/K.mol
∴ T = 79°C ≅ 352 K ⇒ K = ?
⇒ K(79°C) = (5.0 E9 s-1)e∧[ - (16.3KJ/mol)/(8.314 E-3 KJ/K.mol)(352 K)]
⇒ K(79°C) = (5.0 E9 s-1)e∧(- 5.5697)
⇒ K(79°C) = (5.0 E9 s-1)*(3.811 E-3)
⇒ K(79°C) = 1.906 E7 s-1
Answer:
100 and 1 atm
Explanation:
I think the gas is given kinetic energy only from its temperature
Answer:
B) Ksp = 3.7 E-11
Explanation:
CaF2 ↔ Ca2+ + 2F-
S S 2S,,,,,,,,,,,,,,,in the equilibrium
⇒ Ksp = [ Ca2+ ] * [ F- ]²
⇒ Ksp = S * ( 2S )²
⇒ Ksp = 4S³
⇒ Ksp = 4 * ( 0.00021 )³
⇒ Ksp = 4 * 9.261 E-12
⇒ Ksp = 3.704 E-11
