Question

Describe the thermodynamic parameters for the following process as either: 0 or = 0 a. At 1 atm, liquid water is heated above 100 degree C. Delta S_system __ Delta s_universe __ Delta H_system __ Delta G __ b. When a stable diatomic molecule spontaneously forms from Its atoms. Delta S_system __ Delta S_surrounding __ Delta_universe __ Delta H_system __ Delta G __. 3. Given: CH_3COOH(aq) H'M + CH_3COO^- (aq) K_a = 1.75 times 10^-5 at 25 degree C What is AG at 25 degree C for a solution in which the initial concentrations are: [CH_3COOH]_0 = 0.10 M [H^+]_0 = 4.8 times 10^-8 M (CH_3COO^-]_0 = 0.010 M

Explanation / Answer

Q2.

dSsystem --> must increase, since Q increses, and T will increase as well

dSsurrounding --> must decrease, since Q is lost

dSuniverse --> this must be increasing, in order for this to be spontaneous

dHsystem --> increases, since this is endothermic process

dG = must be negative, i.e. it willbe forwarding

B)

diatomic molecule form its atom

dSsystem --> increases, since more molecules

dSsurroundings --> must increase since the system releases enery

dSuniverse --> must decrease

dHsystem--> most likely heat is released due to breaking of bonds

dG > 0, not likely to occur
