=> -½ ∆[N2O]/∆t ---> the -ve sign
indicate that the concentration is decreasing.
N2O must be a reactant and 1/2 indicate that there r 2 moles of N2O
undergoing reaction.
=> ∆[O2]/∆t ---> the +ve sign
indicate that the concentration is increasing.
O2 must be a product and 1 indicate that there is 1 moles of O2
being produced
=> ½ ∆[N2]/∆t ---> the +ve
sign indicate that the concentration is increasing.
N2 must be a product and 1/2 indicate that there is 2 moles of N2
being produced.
Therefore, the balanced reaction is 2N2O ---> 2N2 + O2

The Haber reaction for the manufacture of ammonia is: N2 + 3H2 → 2NH3 Without doing any experiments, which of the following can you say MUST be true? The reaction is not an elementary reaction. The activation energy is positive. Disappearance rate of N2 = 3 (Disappearance rate of H2). Δ[H2]/Δt will have a positive value. Disappearance rate of H2 = 3 (Disappearance rate of N2). Reaction rate = -Δ[N2]/Δt. The reaction is first order in N2.
Reaction rate is expressed in terms of changes in the concentration of reactants and products. Write a balanced equation for the following rate expression: Rate = − (Δ[CH4]/Δt) = − 1/2 (Δ[O2]/Δt) = 1/2 (Δ[H2O]/Δt) = Δ[CO2]/Δt You do not need to include the states of matter in your answer.
