The rate of reaction increases when reactant particles successfully collide more frequently. Temperature, reactant concentration, size of solid reactant particles (surface area) and catalysts can ...

SAN DIEGO--(BUSINESS WIRE)--Reaction Design®, a leading developer of combustion simulation software, announced that new capabilities have been added to CHEMKIN-PRO, the de facto standard software ...

It has to do with the particle size of the solid material, which determines how rapidly a chemical reaction takes place. In this activity, you can try this for yourself—skipping the explosion ...

However, it is often difficult to determine what reaction rates they can achieve, ... the current flow is dependent on the particle size—the smaller the catalyst particle, ...

Particle size distribution affects the packing density of cement particles in a paste, hydration rate, and hydration quantity. A higher packing density allows for denser cement. Water Treatment ...

The diminished surface-area-normalized catalytic activity of highly dispersed Pt nanoparticles compared with bulk Pt is particularly intricate, and not yet understood. Here we report on the oxygen ...

Particle formation during the initial stages of emulsifier-free organotellurium-mediated living radical emulsion polymerization (emulsion TERP) of styrene at 60°C was investigated at two stirring ...

Rates of reaction. The speed of a chemical reaction is affected by temperature, concentration, particle size and the presence of a catalyst. It can be calculated by measuring changes in reactants ...
