What is the effect of Catalysts on Ignition of Ammonium Perchlorate based propellants...???

     A Catalyst is a substance that is used in small amounts relative to the reactants that modifies the rate of reaction without it being consumed in the reaction and this process is called Catalysis. Catalysts that accelerate the reaction are called positive catalysts while the ones that slow down are called inhibitors. Catalysts react with one or more reactants to form intermediate...
