How to set a temperature boundary condition?

Please login with a confirmed email address before reporting spam

A square domain is filled with hydrated salt. There is a heat flux of 1000W / m at the top boundary. The initial temperature is 443k. When the temperature in the domain reaches 473k, the hydrated salt begins to desorb and generate water vapor and solid salt. Where can I set the 473k? I try to set the if function in the reaction rate of the chemical interface, but it has no effect on the result. Is there any other way?
