The correct answer is option B. When the forward and reverse paths of a change occur at the same rate, <span>the system is in equilibrium specifically in dynamic equilibrium.</span> Dynamic equilibrium is
the balance in a process that is continuing. It is achieved in a reaction when
the forward rate of reaction and the backward rate of reaction is at the same
value or equal.
Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
Answer:
(b). Mass and distance.
Explanation:
The gravitational force between two objects is given by Newton's law of universal gravitation. The formula is as follows :

Here,
G is universal gravitational constant
r is the distance between two objects
It is very clear that the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them.
Hence, the two quantities are used to predict gravitational force according to Newton's law of universal gravitation are mass and distance.
Boyle's law which plays a major role in the kinetic-theory states that Volume and Pressure are inversely proportional
