Clicker Question Consider the reaction:H2O(g) + CO(g) H2(g) + CO2(g) At a given temperature, K = 25. If you initially start with 12 M H2O(g) and 12 M CO(g) determine the concentration of CO2(g) at equilibrium. a) 10 M b) 12 M c) 24 M d) 25 M e) I don’t know.

Reaction Quotient (Q)

Clicker Question Consider the reaction:H2O(g) + CO(g) H2(g) + CO2(g) At a given temperature, K = 25. If you initially start with 3.0M H2O(g), 14M CO(g), 42M H2(g), and 52M CO2(g) determine the concentration of H2O(g) at equilibrium. a) 1 M b) 2 M c) 5 M d) 6 M e) I don’t know.

Change in Concentration/Time

Concentration Profile (NH3)

Clicker Question Consider the reaction:N2(g) + 3H2(g) 2NH3(g) At a certain temperature, you initially react 5.0M N2(g) and 12M H2(g) and at equilibrium [NH3] = 6.0M. Determine the value for K at this temperature. a) 0.0083 b) 0.10 c) 0.67 d) 1.0 e) I don’t know.
