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.
In this reaction, since there are more moles of gaseous reactants than gaseous products, reducing the volume will cause the equilibrium to shift to the right. In general, a change in pressure caused by a change in volume has a greater effect on reaction rate than if the number of moles of gas is greater.
