Answer: The rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Explanation:
Rate of a reaction is defined as the change in concentration of products and reactants with respect to time.
The rate of a reaction decreases with times because reactants are converting into products.
As a result, the reaction is proceeding with a decrease in the concentration of reactants due to which less number of collisions between the reactant molecules will be there.
Hence, rate of reaction will decrease.
Thus, we can conclude that the rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Answer:
Explanation:
time to diffuse x cm is given by the relation
t = X² /2D
D = 5.7 x 10⁻⁷
t = X² / 2 x 5.7 x 10⁻⁷ = X² x 10⁷ / 11.4 s
X = 10 pm = 10 x 10⁻¹² m = 10 x 10⁻¹⁰ cm = 10⁻⁹ cm
t =( 10 ⁻⁹)² x 10⁷ / 11.4 = 10⁻¹¹ / 11.4 = 8.77 x 10⁻¹³ s
A substance above its critical pressure is <span>supercritical.

Answer:
Orbitals
Shells
Energy Levels
Explanation:
Elements in the same period will have the same energy levels which is the same as orbitals and shells.
- The period of an element indicates the energy level in an atom.
- Elements in period 1 will have one energy level or shell or orbitals.
- Down a group this is not the case.
- The energy level increases from top to bottom.
- As we go down the group, we are transiting from one period to another.
