(c) Calculate the standard heat of reaction AHr for the reaction of nitrogen monoxide (NO) gas with oxygen (O₂) gas to form nitrogen dioxide (NO₂) gas. The balanced equation for the reaction is 2NO(g) +20₂ (g) → NO₂ (g). Data AH of NO (g) = 90.4 kJ/mol AH of NO₂ (g) = 33,85 kJ/mol [25 Marks] E [7]

=) 12.98 g of KOH was dissolved in 100 ml of distilled water. 7.5 ml of the KOH solution was titrated against HCI. If 0.45 ml of HCI was needed to reach the reaction end point, find the concentration of HCI in g/L. [6] " Concentrated phoophoria goid is 00% H.DO by macs and the

Q5 (a) What is a buffer solution? Give example of a buffer solution containing weak acid and its salt with a strong base. (b) Calculate the pH and the pOH of a solution 0.025 M HCI solution. (c) Give reasons why acetic acid is a weak acid and HCI is a strong acid. (d) Why is it important to maintain a constant pH in blood.
