What statement describes coupling reactions? Two nonspontaneous reactions are coupled together so both become spontaneous. Two spontaneous reactions are coupled together so both become more spontaneous. The spontaneous reaction supplies enough energy for the nonspontaneous to occur. The nonspontaneous reaction makes spontaneous reaction to proceed faster.
(a) Using Gibb's free energy equation, predict whether at 28.0 °C, the following reaction is spontaneous or not: 4 NH3 (g) + 5 O2 (g) 4 NO (g) + 6 H2O (g) (Given: AU = + 9.08 kJ.mol¬' and AS = + 35.7 JK-' mol-') Hint: Use AU and above equation to calculate AH first. (b) Calculate the Change in Gibb’s Free energy for the following reaction and predict whether the reaction is spontaneous under standard conditions or not? 4 KCIO3 (9) — ЗКСІО4 (9) + КCІ () Given: Molecules дн?

Classify each process as spontaneous or nonspontaneous. Spontaneous Nonspontaneous Answer Bank A mixture of N, and O, gas is separated into pure N, and pure O2. The conversion of diamond to graphite at 25 °C and 1 atm. Water at 20 °C gets warmer when a piece of metal heated to 100 °C is added. Ice melts at –10 °C and 1 atm. The dissolution of table salt in hot water.
The band of stability represents nuclei that are not likely to undergo radioactive decay. True False If AH0, the reaction is spontaneous at all temperatures spontaneous at high temperatures spontaneous at low temperatures non-spontaneous at all temperatures At a substance's melting point or boiling point, two phases can exist simultaneously. True False
Many types of cells are able to use membrane-spanning transport proteins and a source of energy to drive the active transport of glucose across the cell membrane. Let’s consider a specific protein that is able to transport (from outside the cell into the cytoplasm) one molecule of glucose for each molecule of ATP the protein hydrolyzes. The details of this process are not important for this problem except that you can treat it like equilibrium process. The overall reaction and the associated ΔG at 298 K for this process are given below. Glc(out) + ATP + H2O ⇌ Glc(in) + ADP + Pi @?=298 K, ΔG=−31.3 kJ mol-1 Additional Information: -Pi is “inorganic phosphate” (i.e. PO43– & related species). At equilibrium, [Pi] = 3 × 10-3 M.-The cell maintains a ratio of ATP to ADP of about 20 i.e. [ATP]/[ADP] = 20).-The maximum ratio of [Glc(in)] to [Glc(out)] occurs when the system is at equilibrium. a) Write an expression for the equilibrium constant for this process.b) Your expression for ?eq in…

Spontaneous chemical reactions proceed until they hit equilibrium. Once the reaction hits equilibrium, it stops until the product or reactant concentration changes. The reaction will then start again until the equilibrium concentrations of reactants and products are restored. If the statement isn’t accurate then tell me why that is the case.
Which statement is true about the relationship between entropy and spontaneity? spontaneous reactions tend to lead to higher entropy entropy is the same as spontaneity as entropy increases, spontaneity decreases as entropy increases, spontaneity is unaffected
