One mole of an ideal gas is expanded isothermally from (T₁, P₁, V₁) to (T₂,

P₂, V₂) in two stages. First stage uses constant opposing pressure P’ and

second stage uses constant opposing pressure P₂. Show that the maximum

value of work produced is given by 2RT{1 −( P₂/P₁)^1/2 } and P’= (P₁ P₂)^1/2

NH4NO3(k) → N2O(g) + 2H2O(g)  reaction happens and N2O gas occurs at 65 C degrees. At first 100 mg ammonium nitrate added to reaction baloon, Decomposition reaction takes place for 85 minutes.gas occuring after the reaction 4.5 cm^3 at 1 bar. find the speed constant and half life.

gas is ideal,vapor pressure of water at 65 C degrees is 187.5mmHg

One mole of an ideal gas is expanded isothermally from (T1, P1, V1) to (T2,

P2, V2) in two stages. First stage uses constant opposing pressure P’ and

second stage uses constant opposing pressure P2. Show that the maximum

value of work produced is given by 2RT{1- square root of (P2/P1) }

and P’= Square root of (P1,P2)

3dm3 of approximately 1.5N sodium thiosulphate was prepared for an experiment you are expected to determine its exact normality by an iodometric titration using potassium dichromate as an oxidising agent. for 10dm3 of 1N potassium dichromate taken in the flask, you observed a constant burette reading of 8.2cm3 of thisulphate solution. what is its exact normality
