How do i sketch a titration curve when given the acid (h2co3 in this case), it's starting ph (5.5), it's pka1 (6.3) and pka2 (10. adding naoh (equivalents added) until reaching a ph of 12.
it sounds very simple to just plot the pka's and connect the dots, but i can't tell where i should start rising sharply to create the equivalence point

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
