Expert Solution
For zero order reactions [A] = [A]o - kt
Where
[A]o = initial concentration = 2.600M
[A] = concentration ate time t = 2.300 M
k = rate constant = 2.50x10-1 M/sec
t = time taken = ?
Plug the values we get t = ([A]o - [A]) / k
= ( 2.600 - 2.300)M / (2.50x10-1 M/sec)
= 1.2 s x ( 1 min / 60 s)
= 0.02 min

For reactions governed by the rate laws below, the concentration
of reactant A is doubled while the concentration of reactant B is
halved. Match the rate law to the change in rate of reaction that
would be observed. (does the rate of the reaction double, decrease
by half, quadruple, or is there no change?)
Rate = k[A][B]
Rate = k[A]^2[B]0
Rate = k[A][B^]2
Rate = k[A]^3[B]^2
