The integration constant may be evaluated by a determination of the equilibrium at one temperature, or approximately by means of the Nernst heat theorem. By the first method the constant is 2.6253. (K p = 0.000273 at t=880° C.) That is wrong, because 2 of the units on the top cancel 3 of the units in the bottom. So the units are (1/moldm^-3) and not (0/moldm^-3). And, because you are NOT allowed to leave the units as (1/moldm^-3), you would write your final answer as either (mol^-1dm^3) or (dm^3mol^-1). Let me explain this with a simple example. The equilibrium law. The equilibrium law, sometimes called the law of mass action, says that in a system at equilibrium the activities of the products raised to the powers of their stoichiometric coefficients divided by the activities of the reactants raised to the power of their stoichiometric coefficients is constant at constant temperature. When a reaction component is a gas, we can also express the amount of that chemical at equilibrium in terms of its partial pressure. When the equilibrium constant is written with the gases in terms of partial pressure, the equilibrium constant is written as the symbol K_\text p K p The integration constant may be evaluated by a determination of the equilibrium at one temperature, or approximately by means of the Nernst heat theorem. By the first method the constant is 2.6253. (K p = 0.000273 at t=880° C.)
The Equilibrium Law For any general reaction system the value of Keq is called the equilibrium constant for the reaction. for example: 3 H2(g) + N2(g) <=====> 2 NH3(g) + heat Keq = [NH 3] 2 In other words, there is a constant value that describes the yin and yang of a chemical reaction.

The equilibrium constant is 1.6 × 10 2. Note that dimensional analysis would suggest the unit for this Kc value should be M−1. However, it is common practice to omit units for Kc values computed as described here, since it is the magnitude of an equilibrium constant that relays useful information.
Apr 22, 2005 · It is quite simple. You find m*c*DT for both of the "waters". You know the mass of both, the specific heat capacity (c) is 4190, and you know the initial temperature of both systems. You want to find the final temperature. m1*c*DT1 + m2*c*DT2 = 0 so you get 0.045*4190*(Tf-4) + 0.15*4190*(Tf-75) = 0 Then you just solve it algebraically.
There are all sorts of calculations you might be expected to do which are centred around equilibrium constants. You might be expected to calculate a value for K c including its units (which vary from case to case). Alternatively you might have to calculate equilibrium concentrations from a given value of K c and given starting concentrations.
