The rate of decay of a chemical involved in a reaction that is second order (bimolecular) in one reactant a is given by: = k [aj? -d[a/dt where k is the reaction rate coefficient. derive an expression for the half-life of a in terms of k and the concentration of a at time t-0 (ao)

The gas would begin to expand, and eventually the can would burst or explode.

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
