Explanation:
Detailed explanation-1: -The required balanced chemical equation is: 2KNO3(s)→2KNO2(s)+O2(g)
Detailed explanation-2: -Mutual-diffusion coefficients measured on the volume feted frame of refer-ence are reported for KNO3-HzO at 25 over the concentration range 0.025 to 2.61M. The diffusion coefficients decrease monotonically from 1.928x10 9 m2-sec 1 to 1.166>(10 . 9 m -sec 1 as the concentration increases from 0.0 to 2.61M.
Detailed explanation-3: -The given chemical equation represents the decomposition reaction of potassium nitrate to form potassium nitrite and oxygen gas.
Detailed explanation-4: -In the balanced chemical equation, the coefficient of O₂ is equal to 3.
