what are the five principle factors that influence the rate of chemical change - CORRECT
ANSWER-1. chemical nature
2. ability of the reactants to come in contact with each other
3. concentration of reactants
4. temperature
5. availability of rate-acceleration agents called catalysts
for a given reaction, adding a catalyst increases the rate of reaction by - CORRECT ANSWER-
providing an alternate reaction pathway that has a lower activation energy
doubling the concentration of the 1st order
doubling the concentration of the 2nd order - CORRECT ANSWER-doubles the rate
quadruple the rate
lightest gas will have - CORRECT ANSWER-lowest partial pressure
the rate of reaction depends on ________ but the rate constant does not - CORRECT ANSWER-
concentration
for a reaction that is first order with respect to reactant A, and third-order overall - CORRECT
ANSWER-rate=k(A)(B)2
, the rate determining step is - CORRECT ANSWER-the slowest step
the mechanism is - CORRECT ANSWER-produced in one step and consumed in the other and
won't be final product
the difference between the energy of the starting molecule and the highest energy along the
reaction pathway is known as the - CORRECT ANSWER-activation energy
when the direction of an equation is reversed - CORRECT ANSWER-the new equilibrium
constant is the reciprocal of the original
when the coefficients in an equation are multiplied by a factor - CORRECT ANSWER-the
equilibrium constant is raised to the power equal to that factor
The equilibrium law for a heterogeneous reaction is written without concentration terms for -
CORRECT ANSWER-pure solids or pure liquids
When K is very large: - CORRECT ANSWER-The reaction proceeds far toward completion. The
position of equilibrium lies far to the right, toward the products.
When K ≈ 1: - CORRECT ANSWER-The concentrations of reactants and products are nearly the
same at equilibrium. The position of equilibrium lies approximately midway between the
reactants and products.
When K is very small: - CORRECT ANSWER-Extremely small amounts of products are formed.
The position of equilibrium lies far to the left, toward the reactants.
at equilibrium - CORRECT ANSWER-the rates of the forward and reverse reactions are equal
