Chemical Thermodynamics Question 471
Question: A 1 g sample of octane
Options:
A) 5472 kJ/mol
B) 48 kJ/mol
C) 684 kJ/mol
D) 4281 kJ/mol
Show Answer
Answer:
Correct Answer: A
Solution:
- Rise in temperature = 300 - 294 = 6 K
Heat given to the calorimeter
= Heat capacity
= 48 kJ
Molar mass of octane
1 g of octane gives = 48 kJ heat
114 g of octane = 1 mol of octane gives
= 5472 kJ/mol
