In chemical reactions that include a solid as one of the reactants, you can actually change the reaction rate by varying the size of the solid that reacts with the liquid or the gas. How does this ...

To study the isotope effect in cold chemistry reactions, we measured the Penning ionization reaction rates for collisions between metastable helium, 4 He (2 3 S), which we denote He*, and the ...

Does the temperature of the reactants affect the rate of the chemical reaction? Materials for Each Group. Baking soda; Calcium chloride; Water; Graduated cylinder; Balance or measuring spoon (½ ...
