In the diagram, which letter represents the activation energy?

A

B

C

D

The letter that represents the activation energy from the diagram is letter A.

A chemical reaction occurs only when there is collision between the particles of reactants.

These colliding particles become activated with increased kinetic energy.

Activation energy is the energy barrier that must be overcome before a reaction takes place.

From the diagram,

C is the reactants

D is the products

B is the heat of reaction

While A is the activation energy.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
