Which of the following is true according to the law of a conservation of mass for a reaction involving a catalyst?
Open in App
Solution
The correct option is C Mass of reactant = Mass of product
- Catalyst is a substance that causes the reaction to occur faster or slower without undergoing any chemical change itself.
- It does not participate in the reaction.
- Therefore, mass of a catalyst has no effect on the mass of the products formed.
- So, Mass of reactants = Mass of products.
