Pcoeffs

Pressure corrections are based on the following equations:
$$
 \ln{\frac{K_{i}^{P}}{K_{i}^{0}}} = -\frac{\Delta V_{i}}{RT}.P + 0.5\frac{\Delta K_{i}}{RT}.P^{2} 
 $$
with 
$$
 \Delta V_{i} = a_{0} + a_{1}T + a_{2}T^{2}
 $$
and 
$$
 \Delta K_{i} = b_{0} + b_{1}T + b_{2}T^{2}
$$The variables are:
<ul>
<li>K indicating the type of equilibrium constant</li>
<li>coefficient $a_0$</li>
<li>coefficient $a_1$</li>
<li>coefficient $a_2$</li>
<li>coefficient $b_0$</li>
<li>coefficient $b_1$</li>
<li>coefficient $b_2$</li>
</ul>
