<u>Answer:</u>

<u>For A:</u> The 0.0132 grams is required per pound of the body weight.

<u>For B:</u> The dost required for 191 lb patient is 5.96 grams.

<u>Explanation:</u>

  • <u>For A:</u>

We are given:

Medication requirement = 5.98 mg/kg

To convert the given amount in grams per pounds, we use the conversion factor:

1 kg = 2.20462 lb

1 g = 1000 mg

Converting the value into grams per pounds, we get:

\Rightarrow (\frac{5.98mg}{kg})\times (\frac{1g}{1000mg})\times (\frac{2.20462lb}{1kg})\\\\\Rightarrow 0.0132g/lb

Hence, the 0.0132 grams is required per pound of the body weight.

  • <u>For B:</u>

To calculate the amount of medication for 191 lb patient, we use unitary method:

For 1 lb body weight, the amount required is 0.0132 grams.

So, for 191 lb body weight, the amount required is \frac{0.0312g}{1lb}\times 191lb=5.96g

Hence, the dost required for 191 lb patient is 5.96 grams.

Consider the reaction 3CH4(g)→C3H8(g)+2H2(g).
padilas [110]

From the calculations performed, the free energy change for the reaction is 72 kJ/mol.

<h3>What is the equilibrium constant?</h3>

The equilibrium constant is a value that shows the extent to which reactants have been converted to products.

Given that the equation of the reaction is;

3CH4(g)→C3H8(g)+2H2(g)

Then;

PC3H8 = 0.013 atm

PH2 =  2.3×10−2 atm

PCH4 = 41 atm

Now;

ΔG = ΔG° + RTlnQ

ΔG°reaction = ΔG°products - ΔG°reactants

ΔG°reaction = [( -23.4) +2(0)] - 3(-50.8)

ΔG°reaction = 129 kJ/mol

Q = PC3H8 * PH2^2/PCH4^3

Q = 0.013 * (2.3×10−2)^2/( 41)^3

Q = 6.877 * 10^-6/68921

Q= 9.9* 10^-11

Hence;

ΔG = 129 * 10^3  + [8.314 * 298 * (ln  9.9* 10^-11 )]

ΔG = 129 * 10^3 - 57073

ΔG = 72 kJ/mol
