The ionizationenergyof hydrogenatomis 1.312 xx 10^(6) J mol^(-1)calculatethe energyrequirefor jumpof electron from n=1 ton=2

Answer»

`9.56 xx 10^(5) j//mol`
`7.56 xx 10^(5) j//mol`
`9.84 xx 10^(5) j//mol`
`8.51 xx 1 0^(5) j//mol`

Solution :`Delta E= 1.312 xx 10^(5) ((1)/(n_(1)^(2)) -(1)/(n_(2)^(2))) mol^(-1)`
`=1.312 xx 10^(6)((1)/(1)-(1)/(4))`
`=9.84 xx 10^(5)J mol^(-1)`
