Calculate the rate of heat required to bring 7.20 mol/hr of hbr gas from 43.0 degree c to 225.0 degree c at atmospheric pressure.

the rate of heat required is 38185,056 J/h

Explanation:

for gases, heat is given for the expresion:

∴ 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

the answer for sodium is 0.186

the answer for rubidium is 0.251

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
