    Ep is zero at mean position and max at amplitude. there will be no graph in negative region as energy is scalar. So, the graph will be like we get in full-wave rectification of a.c current.

    only those reactants will take part in the slowest step if their order of reaction is other thn zero order. For step 1 slowest, no H+ takes part in reaction so its zero order and other two are first order. For step 2 to be slowest, all will be 1st order because HOI is proportional to the conc...

    for question 11 look at the first equation..in order to increase the concentration of HOCL we need to make the reaction forward bias. So,by acidifying the water reaction will proceed in forward direction according to Le chatelier principle. As acidity increase more OH ion will be produced to...
