Reference no: EM13180532

Glass will dissolve in concentrated solutions of either NaOH or KOH. At 25C the two reactions below tae place at the same rate. 4NaOH + SiOH2 -->Na4SiO4 + 2H2O is reaction 1. reaction 2 is 4KOH + SiO2 ---> K4SiO4 + 2H2O

However, at 100C glass dissolves in NaOH ten times faster than KOH. Which reaction has the larger value of Ea, the activation energy?
