Question

10) Write a balanced reaction for which the following rate relationships are true. 1 Δ[N2] = Δ[02] = 1 Δ[N20] Rate- 2 At

Answer 1

=> -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
