Question- The elimination of carbon dioxide from pyruvate ions by a decarboxylase enzyme was monitored by measuring the partial pressure of the gas as it was formed in a 250 mL flask at 293. In one experiment, the partial pressure increased from zero to 100 Pa in 522 s in a first-order reaction when the initial concentration of pyruvate ions in 100mL of solution was 3.23 mmol L^-1. What is the rate constant of the reaction?
I am stuck in between this question please help me out
