Calculate the free energy change per mole for the following reactions. (1) CaCO,(s) + CaO(s) + CO,(g) 298K V AH = 1179 kJ, AS = 160,43K- |
|
Answer» The Gibbs free energy change of the reaction is -130.1 kJ and the reaction is spontaneous in nature.Explanation:For the given chemical EQUATION:CaCO3 + CaO+CO(9)To calculate the Gibbs free energy of the reaction, we use the equation:AGAH-TASwhere,AH = enthalpy change = +177.9 kJ = 177900 J (Conversion factor: 1 kJ = 1000 J)T = Temperature = 298 KAS = entropy of the reaction = -160.4 J/KPutting values in above equation, we GET:AG 177900J (298K × (-160.4J/K))AG = -130100.8J = -130.1kJFor a reaction to be spontaneous, the Gibbs free energy of the reaction must be negative.#BrainLock. |

Q1. READ THE STORY. THEN ANSWER THE QUESTIONS. (6) There were once a young husband and wife, and their names were Fred and Kate. Fred had saved a very pretty sum of money, and he changed it all to gold, and said to Kate, “Do you see these yellow counters? I am going to make a hole in the stable underneath the cows' manger and bury them; see that you do not meddle with them, or it will be the worse for you.” And she said, “Oh no, Fred, certainly I won't.” Now, one day when Fred was away, there came some peddlers’ to the village, with earthen pots and basins to sell, and they asked the young wife if she had nothing to give in exchange for them. “O good men,” said Kate, “I have no money to buy anything with, but if you had any use for yellow counters, I might do some business with you.” “Yellow counters! Why not? We might as well see them,” said they. “Then go into the stable and dig under the cows' manger, and you will find them; but I dare not go near the place.” So those rogues went and dug, and found the gold accordingly. And they seized it quickly, and ran off with it, leaving the pots and pans behind them in the house. Kate thought she must make some use of her new possessions, so, as she had no need of them in the kitchen, she spread them out on the ground, and then stuck them, one after another, for ornament, on the fence which ran round the house. When Fred came home and saw the new decorations, he said, “Kate, what have you been doing?” “I bought them every one, Fred, with those yellow counters that were buried under the manger, and I did not go there myself; the peddlers’ had to dig them up for themselves.” “O Kate!” cried Fred, “what have you done? They were not counters, but pure gold, and all our capital; you should not have done so.” “Well, Fred, I did not know; you should have told me that before,” answered Kate. Then Kate stood still a little while to consider, and at last she said, “Listen, Fred, we may be able to get the gold back again. Let us run after the thieves.” (A) ANSWER EACH QUESTION. (4) 1. What were the names of the young husband and wife? |

Give reason. Why covalent compounds do not ionize in solution? |
|
Answer» Electrovalent COMPOUNDS dissolve in polar SOLVENT like water because the forces of attraction between positive and negative charges become weak in water. But since covalent COMPOUND are MADE up of molecules, they do not ionize in water and hence do not dissolve in water. |

What is the critical solution temperature? Draw and explain the variation of mutual solubility of two liquids which exhibit upper CST. |
|
Answer» Critical solution temperature is the maximum temperature at which the two phase region existsvariation of mutual solubility of water and phenol which exhibit upper CSTAt respective temperature, like 325 K, point A displays water-rich layer's compositionlayer as point A1 shows the composition of phenol-rich layer in equilibrium with A. Between these COMPOSITIONS, every MIXTURE will yield 2 layers of compositions A and Al. OUTSIDE these compositions, the two liquids are soluble mutually at 325 K. Similar behaviour is seen at other temperatures below 338.8 KBy Akshat Nashine |
