At 25°C, K= 0.090 for the reaction H20(g) + Cl20(9) = 2 HOCI(9) Calculate the concentrations of al1 species at equilibrium for each of the following cases. a. 1.0 g H20 and 2.0 g Cl2 0 are mixed in a 1.0-L flask. [H2O] =| M [CL,0] = M [HOC1] = M b. 1.2 mole of pure HOCI is placed in a 2.0-L flask. [H2O] = M [Cl20] = M %D [HOCI] = M

A mixture of 0.422 M H,, 0.376 M I,, and 0.913 M HI is enclosed in a vessel and heated to 430 °C. H,(g) + 1,(g) = 2 HI(g) K. = 54.3 at 430 °C Calculate the equilibrium concentrations of each gas at 430 °C. [H,] = M L] = M [HI] = M

A student ran the following reaction in the laboratory at 290 K: 2NO(g)+Br2 (g) <---> 2NOBr (g) When she introduced NO (g)  0.141 moles of and 0.121 moles of Br2 (g) into a 1.00 liter container, she found the equilibrium concentration of Br2(g) to be 0.0665 M. Calculate the equilibrium constant, Kc she obtained for this reaction. Kc=
