`H_(2)O_(2)overset(1st"order")(to)H_(2)O+1/2O_(2)`. Pressure of `O_(2)` is recorded as:
time (min)`" "` 10 min `" "prop`
`P_(O_(2))` (mm)`" "120" "160`
What is half life?

Text Solution

Verified by Experts

The correct Answer is:
5
`H_(2)O_(2)O_(2)toH_(2)O+1/2O_(2)`
`C_(0)" P_(0)=0`
`(C_(0)-x)" "P_(t)=120`
`0" "P_(alpha)=160`
`KX2.303/10="log"160/40,t_(1/2)=0.693/k=5`
`H_(2)O_(2)toH_(2)O+1/2O_(2)`
