1)500 ml of 0.15 M AgNO3 solution was added to 500 ml of 1.09 Fe2+ solution and the reaction is allowed to reach equilibria at 25C Ag+ +fe3+= fe3+ + Ag for 25 ml of the solution , 30 ml of 0.0832 M KMnO4 were required for oxidation. the equilibrium constant for the reaction at 25C?2) in a question a student was given to find the derivative of the product of two functions f and g. the student by mistake thought (fg)dash=fdashgdash for his question f(x)=x^3 and he got the correct answer . given that g(4) = 1 .which of the following are correct (where g(x)>0.. a. g(x) is decreasing in -infinity to 3 b. g(x) is decreasing in 3 to infinity c. g(x) is increasing in 3 to infinity d. g(x) is increasing in -infinity to 3
