← The rate constant of a reaction becomes six times larger when the temperature rises from 343 K to 363 K. What is its activation energy?
Statement I: In the collision theory, every collision that has more than the threshold energy leads to a reaction. Statement II: The molecules must also meet in the right orientation. Choose the correct option. →
