Question

(x) Calculate the work done during the reaction represented by
the following thermochemical equation at 300 K:
CH4 +202 → CO2 + 2H20
(g) (g) (g) (1)
(R = 8.314 JK-'mol-')
(a) +4.988 kJ
(b) -4.988 kJ
(c) -49.88 kJ
(d)+49.88 kJ

Answer 1

Answer: a)+4.988

Explanation:

Try converting R into kJ

Answer 2

it's (b)
w=-∆nrt
here n=2 substitute the values
