Explanation:
The concept applied here is the application of change of state as such ,
A reversible reaction is one that can go in both ways, that is the forward reaction can react to produce the product and the backward reaction can also react to give back the reactants. In a reversible reaction, no new substances are formed and the heat evolved is not much compared to Irreversible reaction.
An Irreversible reaction is one that can not go in both ways. i.e reactants can react to give products but products cant react to give back the reactants. In irreversible reaction, new substances are formed and a huge amount of heat is evolved.
There is reversibility between melting point and freezing point, the differences is if the solid is melting above its melting point, in such case, it is an irreversible reaction.
Given:
K = 0.71 = Kp
The reaction of sulphur with oxygen is
S(s) + O2(g) ---> SO2(g)
initial Pressure 6.90 0
Change -x +x
Equilibrium 6.90-x x
Kp = pSO2 / pO2 = 0.71 = x / (6.90-x)
4.899 - 0.71x = x
4.899 = 1.71x
x = 2.86 atm = pressure of SO2 formed
temperature = 950 C = 950 + 273.15 K = 1223.15 K
Volume = 50 L
Let us calculate moles of SO2 formed using ideal gas equation as
PV = nRT
R = gas constant = 0.0821 L atm / mol K
putting other values
n = PV / RT = 2.86 X 50 / 1223.15 X 0.0821 = 1.42 moles
Moles of Sulphur required = 1.42 moles
Mass of sulphur required or consumed = moles X atomic mass of sulphur
mass of S = 1.42 X 32 = 45.57 grams or 0.04557 Kg of sulphur
I believe with a simple google search that 99.9
Answer:
the air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
