Given Rate law is:
rate = k[A]^3
rate new / rate old = ([A]new/[A]old)^3
here:
[A]new/[A]old = 3
putting values
rate new / rate old = (3)^3
rate new / rate old = 27
Answer: increase by a factor of 27

The order of each reactant in the following reaction was determined by varying concentration and measuring the change in rate. 2NO(g)+Cl2(g)→2NOCl(g)2NO(g)+Cl2(g)→2NOCl(g) When the concentration of NONO was doubled while the concentration of Cl2Cl2 was held constant, the rate increased by a factor of 2. In a separate experiment, when the concentration of Cl2Cl2 was halved while the concentration of NONO was held constant, the rate decreased by a factor of 4. What is the overall reaction order? Express your answer...

The half-life of a reaction,
t1/2, is the time it takes for the reactant concentration [A] to
decrease by half. For example, after one half-life the
concentration falls from the initial concentration [A]0 to [A]0/2,
after a second half-life to [A]0/4, after a third half-life to
[A]0/8, and so on. on. For a first-order reaction, the half-life is
constant. It depends only on the rate constant k and not on the
reactant concentration. It is expressed as t1/2=0.693k For a...

The reaction A + 2B → Products was studied and found to have the rate law: Rate = k[A][B]2. By what factor will the rate increase if the concentration of B is tripled while the concentration of A is held constant?
Areaction was found to be zero-order in A and third-order in B. Increasing the concentration of A by a factor of 3 and the concentration of B by a factor of 2 will cause the reaction rate to increase by a factor of 2 remain constant increase by a factor of 6 increase by a factor of 8
