Effect of catalyst on equilibrium yield
No impact
Effect of catalyst on rate
Faster rate
Effect of catalyst on cost
Lowers cost
Effect of pressure on cost
Higher pressure higher cost
Effect of pressure on rate
Higher pressure = higher rate
Effect of pressure on equilibrium yield
more moles on LHS
Higher pressure = higher equilibrium yield
Effect of temperature on cost
Higher temp = higher cost
Effect of temperature on rate
Higher temp = faster rate
Effect of temperature on equilibrium yield
exo reaction
Lower temp = higher equilibrium yield
Effect of Increase temperature on equilibrium when the reaction is exothermic
shifts to the LHS
Effect of Decrease temperature on equilibrium when the reaction is exothermic
shifts to the RHS
effect of Increase pressure on equilibrium when the reaction has more moles on LHS
RHS
Fewer moles of gas on the RHS and equilibrium is opposing the increase in pressure.
effect of Decreasing pressure on equilibrium when the reaction has more moles on LHS
LHS
More moles of gas on the LHS and equilibrium is opposing the decrease in pressure.
Effect of increase temperature on value of Kc when exothermic
Decrease
Effect of decrease temperature on value of Kc when exothermic
Increase
Effect of increase temperature on value of Kc when endothermic
Increase
Effect of decrease temperature on value of Kc when endothermic
Decrease
Pressure and Concentration on value of Kc
No change
Energetics- reason why u don’t need MEAN bond enthalpy for O=O bond
Oxygen is the only substance that has O=O bond
In energetics what unit is temperature in
Degree Celsius
