What is the amount of work done when 0.5 mole of methane, CH4 (g), is subjected to combustion at 300 K? (given, R = 8.314 J K-1 mol-1)

A) – 2494 J

B) – 4988 J

C) + 4988 J

D) + 2494 J

Correct Answer: D) + 2494 J

Explanation:

Using the formula W = −PΔV,

+ 2494 J is the amount of work done when 0.5 mole of methane, CH4 (g), is subjected to combustion at 300 K.
