The reaction is first order wrt H2O2 so doubling the H2O2 will double the rate Rate Constant x H2O2 Thus Rate is directly proportional to the volume of H2O2 Hence doubling the volume of hard water would double the rate Detailed calculations 3 H2O2 is about 09 Molar they called for 010Molar KI to be used Molarity of stock solution of appx H2O2 0924 M Molarity of stock solution of KI 010 Molar exp mls H2O2KI H2O 1 50ml 100ml 150 ml 2 100ml 100ml 100 ml 3 50ml 200ml 50 ml Molarities of H2O2 exp    See Answer
