Calculating rate of disappearance
WebDec 28, 2024 · Rate of disappearance is given as − Δ [ A] Δ t where A is a reactant. However, using this formula, the rate of disappearance cannot be negative. Δ [ A] will be negative, as [ A] will be lower at a later time, since it is being used up in the reaction. How to calculate rates of disappearance and appearance? Because remember, rate is ... WebNov 13, 2024 · 4 moles of NH 3 are consumed for every 2 moles of N 2 formed, so the rate of disappearance of ammonia is 2 × (0.27 mol L –1 s –1) = 0.54 mol L –1 s –1. Comment : Because of the way this question is formulated, it would be acceptable to express this last value as a negative number.
