Which among the following reactions is an example of instantaneous reaction under normal conditions ?

Answer»

`2H_(2) + O_(2) to 2H_(2)O`
`N_(2) + O_(2) to 2NO`
`NaOH + HClto NaCl + H_(2)O`
`C_(12)H_(22)O_(11) + H_(2)O to C_(6)H_(12)O_(6) + C_(6)H_(12)O_(6)`

SOLUTION :`NaOH + HCl to NaCl + H_(2)O` is a neutralisation reaction between strong acid and strong base. Hence, it is an EXAMPLE of an INSTANTANEOUS reaction.
