Question 2 5 out of 8 points Consider this equilibrium reaction between carbon monoxide and hydrogen gas, occurring in a sealed flexible container. CO(g) + 3 H2(g) CH4(g) + H2O(g) + heat For each listed stress, choose the direction of the resulting shift. Question Selected Match More H2(g) is added to the container. B. Shift towards products CO(g) is removed from the container. A Shift towards reactants More CH4(g) is added to the container. A Shift towards reactants H20(g) is removed from the container. B Shift towards products The contents of the container are heated up. B. Shift towards products The contents of the container are cooled down B Shift towards products The pressure inside the container is increased A. Shift towards reactants The container is stretched to increase the volume. B Shift towards products

Explanation / Answer

More H2 is added to the container - Shift towards products

CO is removed from the container - Shift towards reactants

More CH4 is added to the container - Shift towards reactants

H2O is removed from the container - Shift towards products

The contents of the container are heated up - Shift towards reactants (forward reaction is exothermic, so increasing heat won'r favor this reaction)

The contents of the container are cooled down - Shift towards products

The pressure inside the container is increased - Shift towards products (increase in pressure favors the reaction where number of moles of gas formed is less)

The container is stretched to increase the volume -  Shift towards reactants (with increase in volume, pressure decreases. Decrease in pressure favors the reaction in which more number of moles of gas are formed)
