If a reaction requires two moles of a single reagent to produce one mole of
product, what is the ratio
of the rate of product formation to the rate of reactant consumption?
What is initial rate?
For a reaction with four (4) reagents, how many experiments are necessary
to determine the order of
the reaction when using the method of initial rates?
When the concentration of a reagent, A, is tripled (holding the
concentrations of all other species
constant), the rate increases by a factor of 1.74. What is the order of
the reaction in A
When the concentrations of both reactants A and B are doubled the rate
increases by a factor of 8. The
reaction is second order in B. Determine the order of the reaction in A.

determine the rate law for

What is a substance that speeds up the rate of a reaction without being
chemically altered called?
