For the reaction
`C_(6)H_(12)(l)+9O_(2)(g)to6H_(2)O(l)+6CO_(2)(g)` , `DeltaH=-936.9kcal`
Which of the following is true ?

A

`-936.9= Delta U -(2 xx 10^(-3) xx 298 xx 3)` kcal

B

`+936.9= Delta U+(2xx 10^(-3) xx 298xx3)` kcal

C

`-936.9 = Delta U -(2xx 10^(-3)xx298 xx 2)` kcal

D

`-936.9 = Delta U+(2 xx 10^(-3) xx 298 xx 2)` kcal

Text Solution

Verified by Experts

The correct Answer is:
A

Use `DeltaH=DeltaU+DeltanRT`
`Deltan= -3 & R= 2xx10^(-1)` kcal .
