I2(s) --> I2(g); dH=62.4kJ/mol; dS=0.145kJ/mol.
The reaction will favor the product at this temperature. Your entropy is positive and your enthalpy is also positive, so this reaction will not be spontaneous at all temperatures. But at room temperature, which is 298K, it will be spontaneous and proceed left to right. (this is the sublimation of iodine)

What information does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
Which direction of the reaction is favored at 298 K?
Toward I2(s) production
What effect does raising the temperature of a chemical reaction?
2SO2(g) + O2(g) 2SO3(g)-The reverse reaction is favored.
Which direction of the reaction is favored at 298 k room temperature use the reaction I2s I2g when H 62.4 kJ.mol-1 and S 0.145 kJ.mol-1.k-1?
Gas phase Iodine in open cylinder
What does it mean keq 1?
products are favored over reactants in the reaction.
When a reaction is at equilibrium increasing the temperature favors the reaction that releases energy as heat.?
This is False!!! According to LeChatlier's Principle, increasing the temperature is a strees on the equilibrium. To relieve that stress the reaction will shift producing more of the substances on the side of the reaction that absorbs heat energy.
If a chemical reaction has reached equilibrium and you lower the pressure of the system while keeping the temperature constant what happens to the equilibrium of the reaction?
If all the reactants occupy more volume than all of the products, the reverse reaction will be favored. If all the reactants occupy less volume than all of the products, the forward reaction will be favored. If the products and reagents have the same volume, the equilibrium will not change.
What does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
What effect does increasing the pressure have on this equilibrium?
the forwrd reaction is favored
What information does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
What happens when there is a very high k value in an equilibrium reaction?
Forward reaction favored, concentration of products is higher
Which direction of the reaction is favored at 298 K (room temperature)?
Toward I2(s) production
What does it mean if Keq equals 1?
Products and reactions are equally favored in the reactions
What happens to the equilibrium if the pressure is increased?
equilibrium will shift to the side of the equation with the least moles in attempt to reduce pressure in the haber process N2+3H2 <--> 2NH3 an increase in pressure causes equilibrium to shift the right because it has the least moles (2 instead of 4) <--> represents a reversible reaction sign
Which direction of the reaction is favored at 298 K?
Toward I2(s) production
What effect does raising the temperature of a chemical reaction?
2SO2(g) + O2(g) 2SO3(g)-The reverse reaction is favored.
What information does the rate constant give the rate law?
It tells how much the reaction rate is affected by concentrations.
