1.	Methanol is manufactured by following process CO (g) + 2H_(2) (g) overset(ZnO//Cr_(2)O_(3))hArr CH_(3)OH (g) DeltaH^(@) = - 91 kJ Which of the following step would increase concentration of CH_(3)OH
Answer» increase in temperature ADDITION of He at constant pressure Addition of `CO (g)` Removal of catalyst Solution :(1) exothermic reaction, on increasing temperature reaction proceeds in backward direction. (2) reaction proceeds in backward direction on adding He at constant pressure ltbrrgt (3) addition of CO, INCREASES product concentration. (4) No effect on EQUILIBRIUM.
