Catalysts increase reaction rates by lowering the activation energy of a reaction.
Setler [38]
The answer is true, catalysts increase rates by lowering the activation energy of a reaction. Catalysts lower the reaction energy and so the reaction occurs faster. Enzymes perform the role of biological catalysts. Most metabolic pathways of the body are controlled by enzymes. Enzymes by classification are proteins. <span />

How many liters of nitrogen gas are needed to make 25 mol of nitrogen trifluoride
ikadub [295]
The reaction between N₂ and F₂ gives Nitrogen trifluoride as the product. The balanced equation is;

N₂ + 3F₂ → 2NF₃

The stoichiometric ratio between N₂ and NF₃ is 1 : 2
Hence, 
  moles of N₂ / moles of F₂ = 1 / 2
  moles of N₂ / 25 mol        =  0.5
           moles of N₂            =  0.5 x 25 mol = 12.5 mol
 
Hence N₂ moles needed  = 12.5 mol

At STP (273 K and 1 atm) 1 mol of gas = 22.4 L

Hence needed N₂ volume = 22.4 L mol⁻¹ x 12.5 mol
                                          = 280 L
