What is a reversible reaction
The value of KC is given by this ratio
What is [products]/[reactants]
This method can be used to solve for 'x' for ALL cases
What is the quadratic formula
This principle states that a system at EQ put under stress will try to undue the stress.
What is Le Chatelier's Principle
This process is used to produce ammonia NH3
What is the Haber process
The state when rate_forward equals rate_reverse
What is equilibirum
This value of K favours the reactants.
What is K is less than 1
This method can be used in cases where the initial concentrations of reactants are the same
What is the Perfect Square method
Adding this to an EQ system has no effect on the favourability of the system (i.e. no shift)
What is a catalyst.
Carbon monoxide poisoning can be treated by changing these conditions to oxygen.
What is concentration and pressure.
This types of reaction has all species in the SAME phase
What is a homogeneous reaction
This value of K favours the products.
What is K is great than 1.
This method can be used when K is really small (ie. K<<1)
What is the Approximation method.
This change occurs when the EQ shifts to the side of fewer gas molecules.
What is a change in volume/pressure.
This EQ system is found in soft drinks and is responsible for the acidification of our oceans.
What is carbon dioxide and carbonic acid
This type of reaction has species in DIFFERENT phases
What is a heterogeneous reaction
This type of chart is used to solve for EQ concentrations.
What is an ICE chart.
This variable is used to represent the initial concentrations when EQ concentrations are known
What is 'y'
This reaction is favoured when the temperature of an EQ system is INCREASED
What is the endothermic reaction.
The Contact Process is a multi-step process. The second step of this process occurs under low pressure because of this product.
What is sulfur trioxide (SO3)
At equilibrium, these don't change.
What is concentration
The exponents for the K expression are taken from this component of the chemical reaction.
What are the stoichiometric coefficients.
This effect occurs when we add more ions to a solution already containing that ion
What is the common ion effect.
The Oswaldt process is a multistep synthesis that produces nitric acid. The second step is an exothermic reversible. Decreasing the temperature shifts the reaction in this direction.
What is the forward direction/ to the right.
