Answer:a) 11.34 g of ethane can be formed
b) is the limiting reagent
c) 3.44 g of the excess reagent remains after the reaction is complete
Explanation:
To calculate the moles :
1.
2.
According to stoichiometry :
1 mole of require 1 mole of
Thus 0.378 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
moles of left = (2.10-0.378) = 1.72 moles
mass of left=
According to stoichiometry :
As 1 mole of give = 1 mole of
Thus 0.378 moles of give =
of
Mass of
Thus 11.34 g of ethane is formed.
Answer:
Explanation:
Equilibrium system: It is defined as that condition when the rate of forward reaction is equal to rate of backward reaction.
It is also defined as that condition concentration of reactantsx and concentrations of products are constant .
Suppose a reaction
Equilibrium constant,
Equilibrium constant,
When the reaction is not in equilibrium then reaction constant
When the reaction is in equilibrium then the equilibrium constant is equal to reaction constant
Hence,
When Q < K then the concentrations of reactants are greater than the concentrations of products.
When Q > K then the concentrations of products are greater than the concentration of reactants.
