Please help quickly! i will mark brainliest
bogdanovich [222]

Answer:

Energy of the Reactant: increases

Energy of the product: not at all

Rate of reaction: increases

Enthalpy: not at all

Activation energy: decreases

Explanation:

Catalyst is a substance that increases the rate of reaction than normal to form a product.

Catalyst affect differently to different factors of reaction. A catalyst is meant to increase rate of reaction by lowering the activation energy, so that collision between reactant increase and that passes the energy barrier to form the product faster.

Catalyst has no effect on Enthalpy as change in enthalpy only depends on the chemical compositions of the reactants and products.

Catalyst also increases energy of reactant so that they can collide faster than before and do not affect the energy of product at all.

Hence, the correct answer is:

Energy of the Reactant: increases

Energy of the product: not at all

Rate of reaction: increases

Enthalpy: not at all

Activation energy: decreases

prohojiy [21]

Answer:

<u>Mass:</u>

1) Definition : Mass is the quantity of matter possessed by the body.

2) Quantity : Mass is a scalar quantity

3) Measurement: Mass is measured by ordinary balance

4) Unit : Unit of mass is kilograms in SI units.

5) Formula : m = W/g

<u>Weight:</u>

1) Definition: The gravitational force of attraction is called weight.

2) Quantity : Weight is a vector quantity.

3) Measurement : It is measured by spring balance

4) Unit : Unit of Weight is Newton in SI units.
