Answer: 13.888g
Explanation:
CaCO3 —> CaO + CO2
From the equation above, 1mole of CaCO3 produces 1mole of CaO. Since the answer is to be expressed in grams, let us covert this mole to grams. This is illustrated below:
MM of CaCO3 = 40 +12 + (16x3) = 40 + 12 + 48 = 100g/mol
MM of CaO = 40 + 16 = 56g/mol
From the equation,
100g of CaCO3 produced 56g CaO
Therefore, 24.8g of CaCO3 will produce Xg of CaO i.e
Xg of CaO = (24.8 x 56) / 100 = 13.888g
Therefore, the theoretical yield of CaO is 13.888g
Explanation:
The given reaction equation is as follows.
So, rate constants for different reactants and products written as follows.
As per the reaction equation, the stoichiometric coefficients of reactants and products are as follows.
A = -2
B = -1
C = 1
Therefore,
Hence, 
= 
= 12.5 
Thus, we can conclude that 
and 
are 12.5 .
