Variation of `log_(10)K` with `(1)/(T)` is shown by the following graph in which straight line is at `45^(@)` , hence `Delta H^(@)` is:

A

`+4.606` cal

B

`-4.606` cal

C

2 cal

D

`-2` cal

Text Solution

Verified by Experts

The correct Answer is:
B
Slope of plot `= (-Delta H^(@))/(2.303 R) = 1`
`implies Delta H^(@) = - 2.303xx2 = - 4.606` cal
