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?
Toward I2(s) production
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
Which direction of the reaction equilibrium is favored at 298 K room temperature use the reaction I2 solid to I2 gas when H 62.4 kJmol and S 0.145 kJmolK?
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 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.

What does it mean keq 1?
products are favored over reactants in the reaction.
What does it mean if keq is more than 1?
reactants are favored over products in the reaction
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 it mean to reason mathematically?
product and reaction are equality favored in the reaction
What effect does increasing the pressure have on this equilibrium?
the forwrd reaction is favored
What does it mean 1½?
products are favored over reactants in the reaction.
