2 cards from this section. Quick, good the night before a test.
What is Le Chatelier's principle?
Think about what happens when concentration changes.
How does an increase in pressure affect equilibrium?
Consider the reaction stoichiometry.
Which way does equilibrium shift if pressure is increased in a reaction with unequal moles of gas on each side?
Think about counting moles of gas on both sides.
True or False: Le Chatelier's principle applies to all states of matter.
Consider how solids and liquids respond to pressure.
A equilibrium mixture contains 1.0 M of H2(g), 0.5 M of I2(g), and 1.5 M of HI(g) at constant temperature. If the volume is decreased, explain how the system will respond.
Count the total moles of gas on each side.
For the reaction: aA(g) + bB(g) ⇌ cC(g) + dD(g), where a + b > c + d, how would increasing the pressure affect the equilibrium?
Think about counting the total gas moles and how pressure affects them.
