A spontaneous process…….
a. proceeds without any outside intervention.
b. proceeds when ΔG is negative.
c. proceeds with gain in entropy, ΔS is positive.
d. proceeds with all of the above.
spontaneous reaction proceeds when entropy is increasing and enthalpy is decreasing. process proceeds without intervention.
and with enthalpy negative and entropy positive, the delta G is negative always.
so answer is option d. : proceeds with all of the above.

Entropy ΔS. a. Under what conditions is ΔS<0 for a spontaneous process? b. You are told that ΔS=0 for a process in which the system is coupled to its surroundings. Can you conclude that the process is reversible? Justify your answer. c. Under what conditions does the equality ΔS=ΔH/T hold?
Chapter 18 Thermodynamics Homework 1.Predict the sign of AS for each process: a) The boiling of water b)2HgO(s)-2Hg(I) + 02(s) c) CaCO, (s)CaO(s)+ CO (g) 2. Is the following process spontaneous or nonspontaneous at a given temperature? NaNO,(s) ->NaNO,(aq) 3. If a reaction has ΔS < 0 and ΔΗ < 0 will the reaction always be spontaneous, spontaneous at low T, spontaneous at high T, or never spontaneous? 4.Consider this reaction: Calculate ΔG at 25 °C and determine whether the...
any spontaneous process, the entropy of the system increases. All spontaneous processes are accompanied by a decrease in free energy Question 2 In which state would two moles of Ar(g) have the lowest entropy?! at 45 °C in a volume of 10.0L All the listed conditions have the same entropy! at 150 °C in a volume of 10.0L at 150 °C in a volume of 2.5 L at 45 °C in a volume of 2.5 L Question 3 Which of...
the first one is supposed to be meant spontaneous. thanks ction to be non-spontaneous at any temperature, which of the following В. Tur a chemical reaction to b conditions must be met? AS > 0, AITO AS > 0, AIT <0 AS <0, AHP <0 AS <0, AHP>0 D. 2. Place the following in on lowing in order of decreasing standard molar entropy. N204(8) NO(g) NO2(g) 204 > NO2 > NO B) NO > NO2 > N204 E) NO2 >...
The second law of thermodynamics states that for any spontaneous process the entropy of the universe must increase. Explain how this statement (increasing entropy) relates to: lambda G_rxn lambda H_rxn lambda S_rxn For this process under standard conditions. H_2O_($) O longleftrightdoublearrow H_2O(f), circle the correct sign you predict for (a), (b), and (c) and explain your reasoning lambda G_rxn + or - lambda H_rxn + or- lambda H_rxn + or-(d) Explain how temperature affects the sign of lambda G in...
