"Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units

olasank [31]

Answer:

Part a: <em>Units of k is </em> $M^{-2}s^{-1}$ <em> where reaction is first order in A and second order in B</em>

Part b: <em>Units of k is </em> $M^{-1}s^{-1}$ <em> where reaction is first order in A and second order overall.</em>

Part c: <em>Units of k is </em> $M^{-1}s^{-1}$ <em> where reaction is independent of the concentration of A and second order overall.</em>

Part d: <em>Units of k is </em> $M^{-3}s^{-1}$ <em> where reaction reaction is second order in both A and B.</em>

Explanation:

As the reaction is given as

$A+B \rightarrow C$

where as the rate is given as

$r=k[A]^x[B]^y$

where x is the order wrt A and y is the order wrt B.

Part a:

x=1 and y=2 now the reaction rate equation is given as

$r=k[A]^1[B]^2$

Now the units are given as

$r=k[A]^1[B]^2\\M/s =k[M]^1[M]^2\\M/s =k[M]^{1+2}\\M/s =k[M]^{3}\\M^{1-3}/s =k\\M^{-2}s^{-1} =k$

The units of k is $M^{-2}s^{-1}$

Part b:

x=1 and o=2

x+y=o

1+y=2

y=2-1

y=1

Now the reaction rate equation is given as

$r=k[A]^1[B]^1$

Now the units are given as

$r=k[A]^1[B]^1\\M/s =k[M]^1[M]^1\\M/s =k[M]^{1+1}\\M/s =k[M]^{2}\\M^{1-2}/s =k\\M^{-1}s^{-1} =k$

The units of k is $M^{-1}s^{-1}$

Part c:

x=0 and o=2

x+y=o

0+y=2

y=2

y=2

Now the reaction rate equation is given as

$r=k[A]^0[B]^2$

Now the units are given as

$r=k[B]^2\\M/s =k[M]^2\\M/s =k[M]^{2}\\M^{1-2}/s =k\\M^{-1}s^{-1} =k$

The units of k is $M^{-1}s^{-1}$

Part d:

x=2 and y=2

Now the reaction rate equation is given as

$r=k[A]^2[B]^2$

Now the units are given as

$r=k[A]^2[B]^2\\M/s =k[M]^2[M]^2\\M/s =k[M]^{2+2}\\M/s =k[M]^{4}\\M^{1-4}/s =k\\M^{-3}s^{-1} =k$

The units of k is $M^{-3}s^{-1}$

The heat of vaporization of carbon tetrachloride (CCl4) is 197.8 J/g. How much energy is absorbed by 1.35 mol CCl4 when it vapor

const2013 [10]

Energy absorbed from changing the phase of a substance from the liquid phase to gas phase can be calculated by using the specific latent heat of vaporization. Calculation are as follows:

<span> Energy = 1.35 mol CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g </span>

<span>Energy = 41071.88 J</span>
