which has more entropy per mole at a given temprature 2 mol O (g) or 1 mol O2(g)

What is true about 02 (g) + 2HCl (g) AHr 48 kJ mol i. The reaction is non-spontaneous. ii. The products are more stable than the reactants. 1) only 2) i only 4) the following reaction at 25°C? H202 (g) + c12 (g) ASr=-123.2 J mol K AGr=85 kJ mol ¹ 3) both i and ii neither i nor ii

A certain substance has an enthalpy of fusion of 6.65 kJ/mol and an entropy of fusion of 22.8 J/mol/K. Calculate the approximate melting point of the substance. Leave your answer in Kelvin.

Entropy is the randomness of a system. At the molecular level, entropy can be described in terms of the possible number of different arrangements of particle positions and energies, called microstates. The more microstates the system has, the greater its entropy. Another way of looking at entropy is that the universe is moving toward a broader distribution entropy has since been constantly increasing by distributing this energy. Heat distribution from high temperature to low temperature is a another example of this phenomenon. energy. The universe has a constant amount of energy as stated in the first law of thermodynamics. The universe started with low entropy (concentrated in the moment before the "big bang") and the Part A Rank these systems in order of decreasing entropy. Rank from highest to lowest entropy. To rank items as equivalent, overlap them. > View Available Hint(s) Reset Help Greatest entropy Least entropy 1 mol of helium gas at 273 K and 20L 1 mol of 1 mol of helium gas…
