Question

When ethane (C2H6) reacts with chlorine (Cl2), the main product is C2H5Cl; but other products containing Cl, such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. Calculate the theoretical yield of C2H5Cl when 127 g of C2H6 reacts with 207 g of Cl2, assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl.

Answer 1

To calculate the theoretical yield of C2H5Cl, we need to determine the limiting reactant in the reaction between ethane (C2H6) and chlorine (Cl2). This can be done by comparing the moles of each reactant to their stoichiometric coefficients in the balanced chemical equation.

Step-by-step explanation:

To calculate the theoretical yield of C2H5Cl, we need to first determine the limiting reactant in the reaction between ethane (C2H6) and chlorine (Cl2). This can be done by comparing the moles of each reactant to their stoichiometric coefficients in the balanced chemical equation.

The balanced equation for the reaction is: C2H6 + Cl2 → C2H5Cl + HCl

From the equation, we can see that 1 mole of C2H6 reacts with 1 mole of Cl2 to produce 1 mole of C2H5Cl. Therefore, the amount of C2H6 in moles is equal to the amount of Cl2 in moles.
