Products are favored in a chemical reaction taking place at a constant temperature and pressure. Consider the following statements :
(i) The change in Gibbs energy for the reaction is negative.
(ii) the total change in Gibbs energy for the reaction and the surroundings is negative.
(iii) The change in entropy for the reaction is positive.
(iv) The total change in entropy for the reaction and the surrounding is positive.
The statments which are ALWAYS true are :

Options

A. only (i) and (iii)
B. only (i) and (iv)
C. only (ii) and (iv)
D. only (ii) and (iii)

Answer

B

Explanation

Since products are formed in the chemical reaction taking place at constant temperature and pressure, we can say that the reaction is spontaneous
Hence ` Delta G_("reaction ") lt 0`
` Delta S_(" total") gt 0`
