Question

carbon dioxide is eliminated from pyruvate ions by adecarboxylase enzyme through the following first order reaction

pyruvate(l) goes to CO2(g) + acetaldehyde(l)

for a reaction where the system was maintained at 90 degreescelcius the partial pressure of CO2 was monitored in a 250 ml flaskabove the solution. in 522 seconds the partial pressure incrased by100 pa. the initial concentratio of pyruvate ions was 3.23mMin 100ml of solution. calculate the rate constant for the rection.
