A student measures the time it takes for two reactions to be completed. Reaction A is completedd in 12 seconds, and reaction B is completed in 2q seconds. What can you conclude about the rates of the reactions? A. The rate of reaction A is lower
B. The rates of reation A and B are equal
C. The rate of reaction B is lower

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
