Ответ:
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Explanation:
According to the Arrhenius equation,
where,
R = gas constant = 8.314 J/K mol
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Ответ:
83 mL
Explanation:
Use the dilution equation M1V1 = M2V2
M1 = 18 M
V1 = ?
M2 = 6.0 M
M2 = 250 mL
Solve for V1 --> V1 = M2V2/M1
V1 = (6.0 M)(250 mL) / (18 M) = 83 mL
