A voltaic cell is constructed by immersing a strip of silver in a 1.0M AgNO3 solution and a strip of cadmiun metal in a 1.0M Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way. Write the balanced half-reaction that is occurring at the anode?
Calculate: a.the rate constant b.the half-life at 500 C c.how long will it take to decompose 65% of the drug?
