QUESTION
Calculate
△
G
\triangle G
△
G
given
△
H
=
10
kJ/mol
\triangle H = 10 \text{ kJ/mol}
△
H
=
10
kJ/mol
,
T
=
298
K
T = 298 \text{ K}
T
=
298
K
,

ANSWER
△
G
=
−
4.9
kJ/mol
\triangle G = -4.9 \text{ kJ/mol}
△
G
=
−
4.9
kJ/mol
.
△
G
=
10000
−
298
(
50
)
=
10000
−
14900
=
−
4900
\triangle G = 10000 - 298(50) = 10000 - 14900 = -4900
△
G
=
10000
−
298
(
50
)
=
10000
−
14900
=
−
