What must be known for the rate constant to be calculated from the rate law

The reaction rate at known reactant concentrations.

What causes pressure changes of reactants to affect the reaction rate

The frequency of collisions is changed.

How does increasing the temperature affect collisions

It increases the number of high-energy collisions

How is the effect of concentration changes on the reaction rate seen in the rate law

The exponents determine how much concentration changes affect the reaction rate

What does Le Chtelier's principle state

The Le Chtelier's principle states one thing. It is the dynamic equilibrium which is disturbed by changing the conditions and the position of equilibrium moves that makes a change.

What will happen when a reactant is added to a system at equilibrium

The equilibrium of the system will be upset.

What is molality of a solution
