The reaction AB(aq)->A(g)+ B(g)is second order in AB and has a rate constant of 0.0282 M^{-1} s^{-1} at 25 Celsius. A reaction vessel initially contains 250 mL of 0.105 M AB which is allowed to react to form the gaseous product. The product is collected over water at 25 Celsius.

1-How much time is required to produce 115.0 mL of the products at a barometric pressure of 779.9 mmHg. (The vapor pressure of water at this temperature is 23.8 mmHg.)
