GCSE, help :(Watch
N2 + 3H2 ⇌ 2NH3
a. Calculate the theoretical yield of ammonia, NH3, that can be produced by reacting 90 tonnes of hydrogen with an excess nitrogen
b. The actual yield of ammonia is 120 tonnes. Calculate the percentage yield of ammonia
would appreciate any help because triple chemistry is absolutely kicking my arse
b.) Percentage yield is just the ratio of how much product is actually formed to how much would theoretically be formed, summed up in the equation: . This equation works with both masses and moles, so it's up to you which you choose. Using masses, the yield is = 23.5%. Using moles, the yield is = 23.5%. Hence, it's up to you which you use.
