Question
Find AGrn for the reaction:
3 C(s) + 4 Hz(g) → CaHə(g)
Use the following reactions with known values of AG°:
C,Hg(g) + 50,(g) -
3 CO,(g) + 4 H,O(g)
AGNn
= -2074 kJ
C(s) + O2(g)
Co((g)
= -394.4 kJ
2 H2(g) + O2(g)
2 H,O(g)
-457.1 kJ
-
Express your answer in decimal notation rounded to three significant figures.
