What are Alkenyl Halides? give examples?

Explanation

`K _(1) = 4.5 x 10 ^(3) s ^(-1)`
`T _(1) = 10 + 273 K = 283 K`
`K _(2) = 1. 5 xx 10 ^(4) s ^(-1)`
`T _(2) = ?`
` E _(a) = 60 kJ mol ^(-1)`
For Arrhenisus equation
`log "" ( K _(2))/( K _(1)) = ( Ea )/( 2. 303 R) ((1 _(2) - 1 _(1))/( T _(1) T _(2))) `
`log "" ( 1. 5xx 10 ^(4))/( 4.5 xx 10 ^(3 )) = ( 60000 J mol ^(-1))/( 2. 303 xx 8. 314 JK ^(-1) mol ^(-1)) ((T _(2) - 283 _(1))/( 283 T _(2)))`
`T _(2) = 24 ^(@) C`
