Question

Which of the following process are nonspontaneous? Of those that are nonspontaneous, which are impossible? a. A bike going uphill b. A meteor falling to Earth c. Obtaining H_2 gas from liquid water d. A ball rolling downhill Without doing any calculations, determine the sign of the entropy change for each of the following reactions: a. Mg (s) + Cl_2 ___ (g) MgCl_2 (s) b. 2 H_2S (g) + 3O_2 (g) ___2 H_2O (g) + 2 SO_2 (g) c. 2 O_3(g) 3 O_2 (g) d. HCl (g) + NH_3(g) NH_4Cl(s) Get your assignment initialed and then check the key. Correct any mistakes

Explanation / Answer

1. The b and d processes are spontaneous and a & c are non spontaneous, also impossible.

a. If we apply some enrgy by pushing bike it may go uphill.

c. If we apply any electrical current to split the water, H2 generates from it

otherwise the a and c are impossible.

2. a detla S is negative, non spontaneous. solid has less entropy value than liquids and gases.

b. delta S is positive, spontaneous. the no. of moles of products is less where they are more random.

c. delta S is negative, non spontaneous.

d. delta S is negative, non spontaneous.
