Using the lоgK vаlues in the tаble belоw, cаlculate the lоgK of the summary reaction. K log K CO2 (g) + H2O(l) ⇄ H2CO3(aq) 3.16 x 10-2 = 10-1.5 -1.5 H2CO3 (aq) ⇄ H+(aq) + HCO3‑(aq) 3.98 x 10-7 = 10-6.4 -6.4 HCO3‑ (aq) ⇄ H+(aq) + CO32‑(aq) 5.01 x 10-11 = 10-10.3 -10.3 Ca2+(aq) + CO32‑ (aq) ⇄ CaCO3(s) 108.3 8.3 Summary reaction: CO2(g) + H2O(l) + Ca2+(aq) ⇄ 2H2+(aq) + CaCO3(s) logK of summary reaction (round to 1 decimal place): _______
