Solving Equilibrium Problems with RICE Table Techniques

The video tutorial explains how to solve an equilibrium problem using a RICE table. It begins by introducing the problem, which involves calculating the equilibrium constant KC for a given chemical reaction. The tutorial then explains the difference between KC and KP, and how to use a RICE table to determine equilibrium concentrations. By converting moles to molarity and using stoichiometry, the tutorial guides viewers through the process of calculating the equilibrium concentrations and ultimately solving for KC.

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
