500 ml of a H_(2)O_(2) solution on complete decomposition produces 2 moles of H_(2)O . Calculate the volume strength of H_(2)O_(2) solution ?

A solution of H_(2)O_(2) labelled as '20 V' was left open. Due to this some, H_(2)O_(2) decomposed and volume strength of the solution decreased . To determine the new volume strength of the H_(2)O_(2) solution, 10 mL of the solution was taken and it was diluted to 100 mL . 10 mL of this diluted solution was titrated against 25 mL of 0.0245 M KMnO_(4) solution under acidic condition. Calculate the volume strength of the H_(2)O_(2) solution .

The reaction between phosphorus (P_(4)) and hydrogen (H_(2)) can result in the formation of phosphine (PH_(3)) as shown : P_(4)(s)+6H_(2)(g)hArr 4PH_(3)(g) The graph shows the change in concentration of hydrogen for this reaction in which the system was distrubed after four hours. Which of the following could explain the change in hydrogen concentration at time = 4 hours?
