Relate the chemical equilibrium constant to the enthalpy of reaction.
1. When 1.50 mol CO2 and 1.50 mol H2 are placed in a 3.00-L container at 395 °C, the following reaction occurs: . If Kc = 0.802, what are the concentrations of each substance in the equilibrium mixture?2. The reaction has a Kc value of 2400 at 2000 K. If 0.850 M each of N2 and O2 are initially present in a 3.00-L vessel, calculate the equilibrium concentrations of NO, N2, and O2.
For the reaction H2(g) + Br2(g) 2HBr(g), Kc = 81.4 at 385ºC. If [H2] = [Br2] = [HBr] = 1.6 × 10–2 M at 385ºC, which one of the following is correct?
Group of answer choices
The reaction is at equilibrium already.
The reaction will proceed in the forward direction because K > 1.
The reaction will proceed in the reverse direction to reach equilibrium because Q < K.
The reaction will proceed in the forward direction to reach equilibrium.
