dolor m, f (plural dolors) 1  pain of a continuing nature, especially that of rheumatism. 2  sorrow or grief of a continuing nature.
Given the equilibrium equation: H2(g) + Br2(g) 2HBr(g) If the partial pressure of H2 is increased, the equilibrium will shift to the right. If the partial pressure of H2 is decreased, the equilibrium will shift to the left. If the partial pressure of HBr is increased, the equilibrium will shift to the left.
You can see that the variation of density and pressure occurs much rapidly (faster) than the variation in temperature for the same altitude. So the decrease in P will be larger than decrease in T which means by the equation there will be a net increase in volume. if both P and T varies in a similar way, then the net decrease in P will be cancelled by a net decrease in T.
