1.	`C_(4)H_(10)+(13)/(2)O_(2)(g)rarr4CO_(2)(g)+5H_(2)O(l), DeltaH =- 2878 kJ` `DeltaH` is the heat of……….of butane gas.A. `+4.74 V`B. `+0.547 V`C. `+1.09V`D. `+4.37 V`
Answer» Correct Answer - C In the reaction `overset(-10 + 10)(C_(4) H_(10)) (g) + (13)/(2) O_(2) (g) rarr overset(4 CO_(2))(g) + 5H_(2)O (l)` Change in oxidation number of carbon `= + 16 - (-10) = + 26` `:.` Number of electrons involved in cell process will be 26 `E^(@) = (-DeltaG^(@))/(nF) = - ((-2746) xx 1000)/(26 xx 96500) = + 1.09 V`
