Question

The time-independent Schrödinger equation is used in general to characterize a system A. That stops moving. B. Whose potential does not change with time. C. That cannot be described by ?^psi = psi. D. Whose kinetic energy does not depend on time. E. For which the probability of finding the particle at a spot changes but not its total energy. Which reaction or process has the greatest positive change in entropy, delta S? A. H^+(aq) + CI^-(aq) rightarrow HCl(g) B. 2 C_2H_2(g) + 5 O_2(g) rightarrow 4 CO_2(g) + 2 H2O(l) C. 2 Mg(s) + O_2(g) rightarrow 2 MgO(s) D. 2 C_2H_2(g) + 5 O_2(g) rightarrow 4 CO_2(g) + 2 H_2O(g) E. 2 S0_2(g) + O_2(g) rightarrow 2 SO_3(g)

Explanation / Answer

(20) The process that involves in increase in disorderness of the system will associate with increase in entropy.

(A) Involes increase in entropy. Because compared to aqueous state the disorderness of the HCl molecules in gas state is greater and thus entropy.

In all the remaining cases the number of gas particles decrease from left to right and hence entropy will aslo decrease.

(19) (D) whose K.E does not depend on time.
