What will be the equilibrium constant of the given reaction carried out in a 5 L vessel and having equilibrium amounts of A2 and A as 0.5 mol and 2 xx 10^(-6)
Equilibrium constant question? Homework Statement A mixture of 0.229 mol CO2, 0.229 mol of H2, and 0.328 mol of H2O are placed in a 2.0 L container. The...
What does it mean when we say a test statistic is conservative? What is a confounding variable? What is the difference between mechanical equilibrium and balanced force? Why does average total cost decrease when it is less than marginal cost?
Sometimes it’s hard to wrap your head around the concept at first because you think equilibrium means no other forces are involved. However, equilibrium does not mean no forces are in the picture, just that the forces cancel each other out and so there is no change. ...
