QUESTION TWO:

QUESTION THREE:

Which of the following is a solution of a STRONG acid? 0.10 M HCI 1.0 M H2CO3 0.10 M H3PO4 0.10 M CH3COOH The pKa of acetic acid is 4.75. If acetic acid is found in a solution with a pH of 9.0, which of the following is true? Acetic acid exists predominately in the protonated form. Acetic acid exists predominately in the deprotonated form. The concentrations of the protonated and the deprotonated form of acetic acid are equal. One of the ways catalysts increase reaction rates is by Providing a surface for the reaction to occur. Increasing the activation energy requirement of the reaction. Converting a reaction from an endothermic reaction to an exothermic reaction. Catalysts do not increase reaction rates; they decrease reaction rates.
