Reaction Rates and Equilibrium

Flashcards about Reaction Rates and Equilibrium based on lecture notes.

__ states that when a system at equilibrium has a stress applied, the system will respond by shifting equilibrium to minimize the effect of the stress.

Le Chatelier’s Principle

According to LeChatelier's Principle, examples of variables that can affect equilibrium are __.

Concentration, Temperature, Pressure-Volume of gaseous systems, non-reactant/product gas, catalyst

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, increasing N2, will shift the reaction __.

right or towards products

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, decreasing H2, will shift the reaction __.

left or towards reactants

Inhibitors __.

raise the activation energy

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, increasing the temperature, will shift the reaction __.

left or towards reactants

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, increasing pressure, will shift the reaction __.

right or towards products

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, increasing volume, will shift the reaction __.

left or towards reactants

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, adding Argon gas (or something that isn’t part of the system), will shift the reaction __.

nowhere (no shift)

According to LeChatelier's Principle, for the reaction N2 (g) + 3 H2 (g) 2 NH3 (g) H = -92 kJ/mol, adding a catalyst, will shift the reaction __.
