Question

please help me match what goes in blank?! Chatelier's principle slates that when equilibrium is disturbed, the rates of the forward and reverse reactions change to relieve that stress and re-establish This tutorial, you will learn the basic principles of chemical equilibrium and use Le Ch telier's principle to predict the equilibrium shift for reversible reactions. Identity the stress Consider the equilibrium reaction CO(g) + H2O(g) CO2(g) + H2(g) Determine how each change in the left-hand column will stress the system and in which direction the equilibrium reaction will shift in response. Drag the appropriate labels to their respective targets.

Explanation / Answer

In the given reaction,

CO(g) + H2O(g) <===> CO2(g) + H2(g)

According to LeChatellier's principle we would have,

Change                                        System stress                                       Equlibrium shift

Add CO(g)               Reverse reaction rate temporarily decreases           Increase product

Remove H2O(g)      Forward reaction rate temporarily decreases           Increase reactant

Add CO2(g)             Reverse reaction rate temporarily increases            Increase reactant

Remove H2(g)         Forward reaction rate temporarily increases            Increase product
