Increase in number of moles implies increase in pressure and vice visa.  If the forward reaction proceeds by decreases in number of moles (pressure), an imposed increase pressure will favour forward reaction.  Reverse is the case if it proceeds by increase in number of moles (pressure). In other words, when high pressure is applied, equilibrium will shift to the side with less number of moles while when low pressure is applied, equilibrium will shift to the side with greater number of moles.<br \/>\n<img decoding=\"async\" align=\"left\" src=\"https:\/\/ecolebooks.com\/nigeria\/wp-content\/uploads\/9jalessonsimages\/100423_1045_Week3SS2Se4.png\" alt=\"\"\/>N<sub>2(g)<\/sub>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0+\u00a0\u00a0\u00a0\u00a03H<sub>2(g)\u00a0\u00a0\u00a0\u00a0<\/sub>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a02NH<sub>3(g)<\/sub><br \/>\n\t1 mole\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a03 moles\u00a0\u00a0\u00a0\u00a0         2 moles<br \/>\nIncrease in pressure favours forward reaction while decrease in pressure favours backward reaction<\/p>\n<p>\u00a0<strong>EFFECT OF CATALYST<br \/>\n<\/strong>A catalyst does not change (affect) the position of equilibrium.
