Answer:
Theoretical yield of HI is 512 g.
The percent yield for this reaction is 25%.
Explanation:
Moles of hydrogen gas = 3.0 moles
Moles of iodine gas = 2.0 moles
According to reaction 1 mol of hydrogen gas reacts with 1 mol of iodine gas.
Then 3.0 moles of hydrogen gas reacts with 3.0 mol of iodine gas. But there are 2.0 moles of iodine gas. Hence,Iodine is a limiting reagent. The production of HI will depend upon iodine gas moles.
According to reaction , 1 mol of iodine gas gives 2 moles of HI.
Then 2 moles of iodine gas will give:
of HI
Theoretically we will get 4 moles of HI.
Theoretical yield of HI = 4 mol × 128 g/mol= 512 g
Experimental yield of HI = 1.0 mol
= 1 mol × 128 g/mol= 128 g
The percent yield for this reaction is 25%.
The initial volume of the gas is 39 L, option C is the correct answer
<h3>What is the combined Gas Law?</h3>According to combined gas law,
PV= nRT
In the Combined Gas Law, if we change either one of the variables the others will also change.
Here , Pressure (P), volume (V), number of mole of gas (n), and temperature (T).
When the moles of the gas is constant , the above equation can be written as ,
The data given in the question is
P = 1.5 atm
V= ? ml
T=325 K
V'= 48 L
P'= 1.2 atm
T' =320 K
Substituting the values in the above formula
Therefore the initial volume of the gas is 39 L, option C is the correct answer
