A sugar cube coated with cigarette ash readily ignites and burns. All of the cigarette ash remains unchanged after the reaction, but the sugar is burned completely. Manufacturers of cigarettes add chemicals that support burnung into the cigarettes. The factor that caused this change in rate is the ☐ a. presence of a catalyst in the ash , increase in surface area ○ b.i c. nature of reactants d. increase in concentration 14K
