Reactants become products before products become reactants Products become reactants before reactants become products Reactants become products only Reactants become products at the same time as products become reactants
Increases the rate and favours the endothermic reaction Increases the rate and favours the exothermic reaction Decreases the rate and favours the endothermic reaction Has no effect on the yield
Increases the rate and favours the smaller volume Increases the rate and favours the larger volume Decreases the rate and favours the smaller volume Increases the rate but has no effect on the yield
