For the reaction 2A(g) ⇌ B(g) + 2C(s) the equilibrium constant is Kp = 3.6 at a particular temperature. The reaction mixture initially contains 2.0 atm of each gas, A and B, and 10.2 g of C. Choose the statement that is true of the reaction mixture as equilibrium is established at that temperature. A) The reaction will proceed to form more A. B) The outcome cannot be predicted since more data are needed. C) The reaction will proceed to...
Consider the generic reaction: 2A + 3B --> 2C Hrxn = -100 kJ If a reaction mixture initially contains 5 mol of A and 6 mol of B, how much heat (in kJ) will have evolved once the reaction has occurred to the greatest extent possible?
