⁴⁰Ar
N(e)=18
N(p)=18
N(n)=40-18=22

⁴⁰K
N(e)=19
N(p)=19
N9n)=40-19=21

⁴⁰Ca
N(e)=20
N(p)=20
N(n)=40-20=20

Answer:

The correct answer is the activation energy for the reaction is lowered.

Explanation:

Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.

Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.

Enzymes does not have any effect in the equilibrium of the reaction.

jolli1 [7]

Explanation:

Given parameters:

Volume of frozen water = 100000m³

Area of the deposit = 160m by 125m

Unknown;

depth of the deposit = ?

Solution:

Volume is the amount of space occupied by a body.

The volume of this ice is given by;

Volume of ice = length x breadth x depth

Since the unknown is depth, we simply solve for it;

Depth = $\frac{100000}{160 x 125}$ = 5m

The ice is about 5m deep
