What is the effect of doubling the concentration of a reactant in a first-order reaction?
The reaction rate doubles.
What is the effect of doubling the concentration of a reactant in a second-order reaction?
The reaction rate quadruples.
What is the effect of increasing temperature on the rate constant (k)?
k increases, leading to a faster reaction rate.
What happens to the rate if the reaction is zeroth order and you increase the concentration of the reactant?
There is no change in the rate.
What is the effect of a large rate constant (k) on the reaction rate?
A larger k means a faster reaction.
What is the difference between reaction order and stoichiometric coefficients?
Reaction order: Determined experimentally, indicates how the rate changes with concentration. | Stoichiometric coefficients: From the balanced equation, do NOT directly determine reaction order.
What are the steps to experimentally determine rate laws?
1. Run multiple experiments with varying reactant concentrations. 2. Measure the initial rates for each experiment. 3. Compare how the rate changes as you change the concentration of each reactant, keeping others constant.
