Understanding Equilibrium and RICE Tables

What is the initial volume of the container used in the reaction?

• 1.00 L

• 0.200 L

• 1.06 L

• 1.57 L

What does Kc represent in a chemical equilibrium?

• Rate of reaction

• Activation energy

• Equilibrium constant for concentration

• Equilibrium constant for pressure

What is the main difference between Kc and Kp?

• There is no difference

• Kc uses molarity, Kp uses partial pressures

• Kc is for solids, Kp is for gases

• Kc is for liquids, Kp is for aqueous solutions

What does the 'I' in RICE stand for?

• Initial

• Intermediate

• Inert

• Increment

In the RICE table, what does 'C' represent?

• Concentration

• Change

• Constant

• Catalyst

How is the direction of the reaction shift determined in a RICE table?

• Towards the side with zero initial value

• Towards the side with more moles

• Randomly

• Towards the side with higher pressure

What is the equilibrium concentration of CH3OH in moles per liter?

• 0.200

• 1.57

• 0.660

• 1.37

How is the equilibrium constant (Kc) calculated?

• Change over equilibrium concentrations

• Initial concentrations over change

• Products over reactants

• Reactants over products

What role does the coefficient of H2 play in calculating Kc?

• It is ignored

• It becomes the exponent for H2's concentration

• It is subtracted from the concentration of H2

• It is added to the concentration of H2

What is the final calculated value of Kc?

• 2.00

• 0.335

• 1.00

• 0.200
