![Problem 8
From the following heats of reaction:
S+ 0,-- So,
2 so, - 2 So, + 0,
AH =- 297 k)
AH = 198 k
Calculate the heat of reaction for
2S+3 0, -- 2 so,
AH = ? k)
Answer: AH=
the reaction is endothermic/exothermic and therefore
releases/absorbs heat.
Problem 9
From the following heats of reaction:
HC,H,0, (1) + 2 0, (g) 2 CO, (g) + 2 H,0 (1)
C (5) + 0, (8) – Co, (8)
H, (g) + 1/2 0, (8) - H,0 (1)
AH =- 875.0 k)
AH = - 394.51 k)
AH =- 285.8 k)
Calculate the heat of the reaction for:
2C (s) + 2 H, (8) + O, (g) – HC,H,0, (1)
AH =? k]
Answer: AH =
release/absorbs heat.
the reaction is endothermic/exothermic and therefore
Problem 10
