The reaction ab-gt ab is second order in ab and has a rate, Ask an Expert

Academics

The reaction AB-> A+b is second order in AB and has a rate constant of 0.0245 M^-1 S^-1 at 25.0 degree celcuis . A reaction vessel initially contains 250.0 mL of 0.108 M AB which is allowed to react to form the gaseous product. The product is collected over water at 25.0 degree celcius. How much time is required to produce 258.0 mL of the products at a barometric pressure of 736.8 mmHg. (The vapor pressure of water at this temperature is 23.8 mmHg.)
