Chapter 14: Q17P (page 476)

Under standard conditions, will the following reaction proceed spontaneously as written?

Fumarate+NADH+H+鈬�succinate+NAD+

Short Answer

Expert verified

The reaction will unfold spontaneously as written.

Step by step solution

01

Concept introduction

A chemical reaction is a procedure that causes one group of chemical components to change chemically into another.

02

Explanation

If 鈭�Go' is known to be negative, the reaction then will proceed as described. By expression, 鈭�Go' is linked to electromotive force 鈭�尉o'.

鈭�Go'=-nF鈭�尉o'

If the reaction's role="math" localid="1663577937953" 鈭�尉o' is said to be positive, the reaction's 鈭�Go' will be negative, which is a requirement for spontaneity.

鈭�尉o'=-0.040Vis the reduction of fumarate.

While 鈭�尉o'=0.315V is the oxidation of NADH. The total electromotive force is positive,鈭�尉o'=0.355V .

Hence, the reaction is spontaneous.
