Write the balanced equation for the reaction of aqueous Pb(ClO3)2 with aqueous NaI.

Chemistry
1 answer:
Kaylis [27]3 years ago
4 0
If it is just a simple double-replacement reaction, then the balanced equation is simply:

Pb(ClO3)2(aq) + 2 NaI(aq) = PbI2 + 2 Na(ClO3)

However, if this is a precipitation reaction, we must identify which compound will precipitate (is insoluble), either NaClO3 or PbI2

NaClO3 is soluble, PbI2 is not. Only the lead cations and iodine anions will participate in the reaction.

thus, the balanced equation is: Pb^(2+)  +  2I^(-)  ==>  PbI2

The reaction 2a → a2​​​​​ was experimentally determined to be second order with a rate constant, k, equal to 0.0265 m–1min–1. if
katovenus [111]

The integrated rate law for a second-order reaction is given by:

\frac{1}{[A]t} =   \frac{1}{[A]0} + kt

where, [A]t= the concentration of A at time t,

[A]0= the concentration of A at time t=0

<span>k =</span> the rate constant for the reaction


<u>Given</u>: [A]0= 4 M, k = 0.0265 m–1min–1 and t = 180.0 min


Hence, \frac{1}{[A]t} = \frac{1}{4} + (0.0265 X 180)

<span>                                        = 4.858</span>

<span><span><span>Therefore, [A]</span>t</span>= 0.2058 M.</span>

<span>
</span>

<span>Answer: C</span>oncentration of A, after 180 min, is 0.2058 M
