1. Calculate Ke for the reaction SnO2(s) 2CO(g) Sn(s) 2CO2(g) + + given the following information: SnO2(s) H2(g) + 2H:(g)Sn(s) + 2H20(g) CO2(g) H2O(g) + CO(g) Ke 8.12 Ke-0.771 2. A sample of HI is placed in a container and allowed to decompose to H2 and I2. The initial concentrations for all chemicals and the equilibrium concentration of HI are provided below. Based on the reaction given, fill in the missing values in the grid and solve for Ke. 2111 2HI Initial concentration Change in concentration Equilibrium concentration 0.0300 M 0 M 0 M 0.0236 MExplanation / Answer
let us number the reactions as 1,2,3 from top to bottom
rxn 1 can be written as:
rxn 1 = rxn2 - 2*rxn 3
so,
Kc1 = Kc2/Kc3^2
= 8.12 / (0.771)^2
= 13.66
Answer: 13.66
