For the first order reaction :
`H_(2)O_(2)(aq)rarrH_(2)O(l)+(1)/(2)O_(2)(g)`.
the half life of reaction is 30 min. If the volume of `O_(@)(g)` collected at a certain pressure and temperature is 100 ml after a long time from the start of reaction, then what was the volume of `O_(2)(g)` collected at the same pressure and temperature, after 60 min from the start of reaction?

A

25 ml

B

75 ml

C

50 ml

D

`12.5` ml
