Answer: 11.25 moles of 
will be required to completely react with 2.25 moles of 
.
Explanation:
The balanced chemical equation is:
According to stoichiometry :
1 mole of require = 5 moles of
Thus 2.25 moles of will require=
of
Thus 11.25 moles of will be required to completely react with 2.25 moles of .
The answer is 123

Answer:
The activation energy is 164.02 kJ/mol
Explanation:
Log (k2/k1) = Ea/2.303R × [1/T1 - 1/T2]
k1 = 8.9×10^-4 s^-1
k2 = 9.83×10^-3 s^-1
R = 8.314 J/mol.K
T1 = 540 K
T2 = 578 K
Log (9.83×10^-3/8.9×10^-4) = Ea/2.303×8.314 × [1/540 - 1/578]
1.043 = 6.359×10^-6Ea
Ea = 1.043/6.359×10^-6 = 164020 J/mol = 164020/1000 = 164.02 kJ/mol
