Show all work, thank you! Aniline (PhNH2, MM = 93.13 g/mol) is a weak base (pKa of PhNH3 = 4.600).a) A 25.0 mL sample of a solution of aniline requires 25.67 mL of 0.175 M HCI to reach the equivalence point in a titration. What is the original concentration of theaniline solution? Round your answer to the correct number of significant figures and enter it into the box below. If your answer is a decimal, include a 0 before the decimalpoint. Do not use scientific notation.concentration of aniline solution = type your answer...Mb) What is the pH of the aniline solution before any titrant has been added? Round your answer to the correct number of significant figures and enter. it into the boxbelow. If your answer is a decimal, include a O before the decimal point. Do not use scientific notation.pH= type your answer...c) What is the pH of the solution after 7.00 mL of titrant have been added? Round your answer to the correct number of significant figures and enter it into the box below.If your answer is a decimal, include a 0 before the decimal point.

All changes save 7. When two solutions are mixed, a color change occurs. The data tables show the time between mixing and the color change for two sets of conditions. For Condition One, the solution concentrations were constant and temperature varied. For Condition Two, the temperature was constant and concentrations varied. Condition One: Concentration Time for Temperature (°C) Sample Color to Change 1 10° 36 sec 22° 14 sec Condition Two: Temperature Time for Concentration Sample Color to % Change 1. 100% 15 sec 2. 50% 24 sec Which of these statements is true according to the data? O The reaction rate is greater at 22°C than at 10°C. O Reducing the temperature increases the rate of the reaction. The reaction is affected by changes in temperature not by changes in concentration. O Decreasing the concentration increases the reaction rate. PREVIOUS 17 of 25 NEXT SAVE & EXIT
