I have a doubt in electrochemistry that I do not understand the reaction taking place at cathode and anode respectively

Posted by Deeksha Bhagwat 7 years, 10 months ago

CBSE > Class 12 > Chemistry

1 answers

Amarvir Amarvir 7 years, 10 months ago

at cathode reduction take place because ( red cat) red means redox and cat means cathode. so reduction means gain of electrons so ions in solution will gain electrons and get attached to the electrod. on the other hana at anode(an ox) an means anode and ox means oxidation so atoms of anode will change into ions by losing electrons

Zero order reaction and its moecularity

Posted by Naveen Sandhu 7 years, 10 months ago

CBSE > Class 12 > Chemistry

1 answers

Mmmmmmmmmmmmmmmmmmmm Wwwwwwwwwwwwwwwwwwww 7 years, 10 months ago

In some reactions, the rate is apparently independent of the reactant concentration. The rates of these zero-order reactions do not vary with increasing nor decreasing reactants concentrations. This means that the rate of the reaction is equal to the rate constant, kk , of that reaction. This property differs from both first-order reactions and second-order reactions.
