Ответ:
No they do not have a lot of kinetic energy
Ответ:
the rate of heat required is 38185,056 J/h
Explanation:
for gases, heat is given for the expresion:
Q ≅ mCpΔT∴ T1 = 43°C + 273 = 316 K
∴ T2 = 225°C + 273 = 498 K
⇒ ΔT = T2 - T1 = 498 - 316 = 182 K
∴ Cp HBr (298 K) = 29.14 J / mol * Kspecific heat tables
⇒ Q = (7.2 mol/h ) * (29.14 J/mol K) * ( 182 K )
⇒ Q = 38185.056 J/h
