Answer:
To speed up a reaction
Explanation:
Heat, as well as catalysts, increase the reaction rate of some chemical reactions since they cause the enzymes or reagents in charge of carrying out the transformation to products to act faster and increase their kinetic energy of reaction.
Answer: 2 PCl3 + 2 Cl2 > 2 PCl5
Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.
For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +
(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.
The chemical reaction will have a balance chemical equation.
