Select the four true statements below describing the standard free energy change (δg) and the equilibrium constant (keq).
options:
1. the standard free energy change is a function of enzyme concentration in the reaction.
2. the value for the equilibrium constant can be experimentally determined for a given reaction.
3. the equilibrium constant is equal to ratio of the concentration of reactants over products at equilibrium.
4. the value for the standard free energy change is constant for a given reaction.
5. the equilibrium constant is the ratio of product and reactant concentrations at equilibrium.
6. if the value of the equilibrium constant is known, the value for the standard free energy change can be determined.
7. a reaction is spontaneous when the standard free energy change and the equilibrium constant are both negative values.

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
