If 175.0g of nitrogen is reacted with 250.0g of hydrogen, what is the theoretical yield of the reaction? What is the excess reactant? What is the limiting reactant? Show your work.

Answers

Answer 1

Answer:

Nitrogen gas is the limiting reactant

Hydrogen gas is the excess reactant

The theoretical yield is 425 g of ammonia

Explanation:

Equation of reaction: 3H2 + N2 ---> 2NH3

From the equation of reaction, 3 moles of hydrogen gas reacts with 1 mole of nitrogen to produce 2 moles of ammonia gas.

Molar mass of hydrogen gas = 2.0 g

Molar mass of nitrogen gas = 14.0 g

Molar mass of ammonia gas = 17.0 g

Number of moles of hydrogen gas in 250 g = 250/2 = 125 moles

Number of moles of nitrogen gas in 175 g = 175/14 = 12.5 moles

Mole ratio of Hydrogen to Oxygen = 125/12.5 = 10 : 1

Therefore, nitrogen gas is the limiting reactant.

Hydrogen gas is the excess reactant

14 g of nitrogen gas produces 17 × 2 g of ammonia = 34 g of ammonia

175 g will produce (34 × 175)/14 = 425 g of ammonia

Therefore the theoretical yield is 425 g of ammonia
