1. lnkc-lnk= -[Eac/RT + lnA] - [-Ea/RT + lnA] ln(kc/k)= Ea-Eac/RT
CH 14 #79-a
SAME FOR BOTH THEREFORE DROPS OUT.
k=-Ea/RT + lnA
Kc IS CATALIZED RATE CONSTANT, Eac IS CATALZED ACTIVATION ENERGY.
lnkc-lnk= -[Eac/RT + lnA] - [-Ea/RT + lnA]
ln(kc/k)= Ea-Eac/RT
ln(kc/k)= 95.5 kJmol-55 kJ/mol/[(8.314J/K*mol)(298K)(1 kJ/1000J)]
(kc/k)=1 x 107

2. lnkc-lnk= -[Eac/RT + lnA] - [-Eac/RT + lnA] ln(kc/k)= Ea-Eac/RT
CH 14 #79-a
A IS SAME FOR BOTH THEREFORE DROPS OUT.
k=-Ea/RT + lnA
Kc IS CATALIZED RATE CONSTANT, Eac IS CATALZED ACTIVATION ENERGY.
lnkc-lnk= -[Eac/RT + lnA] - [-Eac/RT + lnA]
ln(kc/k)= Ea-Eac/RT
ln(kc/k)= 95.5 kJmol-55 kJ/mol/[(8.314J/K*mol)(398K)(1 kJ/1000J)]
(kc/k)=2 x 105

3. 2[NO2(g) + SO2 (g)  NO(g) + SO3 (g) ]
CH 14 #71-
2[NO2(g) + SO2 (g)  NO(g) + SO3 (g) ]
2 NO(g) + O2 (g) 2 NO2 (g)
2SO2 (g) + O2 (g)  2 SO3 (g)
WHERE NO2 IS A CATALYST, IT IS IN THE GAS STATE AS ALL OTHER SPECIES, THEREFORE IT IS A HOMOGENOUS CATALYST.

4. SLOW CH 14 #65 H2(g) + ICl (g)  HI (g) + HCl (g)
Rate = k[H2][ICl]
SLOW
H2(g) + ICl (g)  HI (g) + HCl (g)
HI(g) + ICl(g) I2 (g) + HCl (g)
H2(g) + 2 ICl(g)  I2 (g) + 2HCl (g)
RATE = k[H2][HCl]
Rate = k[HI][HCl]
