28 мар. 2023 г. · Reactions 1, 2, and 3 have a positive ΔSrxn. Explanation: The reaction with a positive ΔSrxn is the one where the total number of gas molecules increases. |
23 апр. 2019 г. · Answer: The reactions that have a positive ΔS rxn are the first and the fourth choices: 2A(g) + B(s) → 3C(g) 2A(g) + 2B(g) → 5C(g) ... |
20 окт. 2015 г. · Which of the following reactions have a positive ΔSrxn? Check all that apply. 2A(g)+B(g)----->C(g) A(g)+B(g)----->3C(g) 2A(g) |
A(g) + B(s) → C(g): This reaction has a positive ΔS because a solid reactant is converted into a gaseous product, increasing the disorder. 2 A(g) + B(g) → 4 C(g) ... |
Chemistry · Chemistry questions and answers · Which reactions have a positive ΔSrxn? A. 2A(g)+3B(g)⟶4C(g) B. A(s)+B(g)⟶2C(g) C. 2A(g)+2B(g)⟶3C(g) D. A(g)+B(g) ... |
Which reactions have a positive ΔSrxn? a. A(s) + 2B(g) -> C(g) b. A(s) + B(g) ... |
Which of the following reactions have a positive ΔSrxn? Group of answer choices. 2 A(g) + B(g) → 4 C(g). A(g) + B(s) → C(g). A(g) + 2 B(g) → C(g). 2 A(g) + B ... |
In this reaction, the number of gas molecules increases from 3 to 4. Therefore, the disorder increases, and ΔSrxn is positive. 2 A(g) + B(g) → C(g). |
24 мар. 2018 г. · Answer: In the reactions A(g) + B(g)------- 3C(g) 2A(g) + B(s)-------3C(g) the number of moles increases, volume increases,so disorder of the molecules |
