based on the following reaction:

2H2O(g) Hidden Assumptions that make Equilibrium Calculations Easier What Do We Do When the Approximation Fails? based on the following reaction: 2H<sub>2</sub>O(g) 2H<sub>2</sub>(g) + O<sub>2</sub>(g) K<sub>c</sub> = 2 x 10<sup>-42</sup> (at 25<sup>o</sup>C) -Starting with only 0.10 M H<sub>2</sub>O(g) , which equation correctly shows the equilibrium concentrations of the reactants and products? ( \Delta C represents the change in concentration of O<sub>2</sub>(g) ) A) B) C) D) E) None of the above 2H2(g) + O2(g)
Kc = 2 x 10-42 (at 25oC)
-Starting with only 0.10 M H2O(g) , which equation correctly shows the equilibrium concentrations of the reactants and products? ( Δ\Delta C represents the change in concentration of O2(g) )
