The reaction 3o2 -> 2o3 has a rate of change of o2 concentation equal to -0.90 mol/l*s. what is the rate of change of o3 concentration

0.6 mol/L.s.

Explanation:

3O₂ → 2O₃,

the rate of the reaction = - 1/3d[O₂]/dt = 1/2d[O₃]/dt

where, d[O₂]/dt is the rate of change of O₂ concentation = - 0.9 mol/L.s.

d[O₃]/dt is the rate of change of O₃ concentration.

∴ d[O₃]/dt = - 2/3(d[O₂]/dt) = - 2/3(- 0.9 mol/L.s) = 0.6 mol/L.s.
