tulislah rumus tetapan kesetimbangan (kc) reaksi berikut! a. 2HI(g) ⇔H2(g) + i2(g) b. CaCO3(s) ⇔CaO(s) +Co2(g) c. 2SO2(g) + O2(g) ⇔2SO3(g) d.2NO(G) + O2(g) ⇔2NO

a) 2HI (g) <=> H2(g) + I2(g)
Kc = [H2] [I2] / [HI]^2

b) CaCO3(s) <=> CaO(s) + CO2(g)
Kc = [CO2]

c) 2SO2(g) + O2(g) <=> 2SO3(g)
Kc = [SO3]^2 / [SO2]^2 [O2]

d)2NO(g) + O2(g) <=> 2NO2(g)
Kc = [NO2]^2 / [NO]^2 [O2]

e) H2(g) + S(g) <=> H2S(g)
Kc = [H2S] / [H2] [S]

f)2C(s) + 2O2(g) <=> 2CO2(g)
Kc = [CO2]^2 / [O2]^2
