Answer:
B.the velocity for the forward reaction equal that of the reverse reaction
Explanation:
A state of rest or motion of a system is described as equilibrium.
For a system to be in equilibrium, the following conditions must be met:
1. It must be involved in reversible chemical process no matter how small the extent of the reversibility.
2. The rate of forward process is equal to the rate of backward or reverse process.
3. The system must be closed.
4. There is no change in the concentration of each of the species in equilibrium with respect to time. There must be a constancy of concentration of each species in the equilibrium process.
When we change any of the conditions of equilibrium, the Le Chatelier's principle comes into play.
The principle states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
Hey there!
Elements and compounds are purely homogeneous substances and they have a constant composition throughout. Elements and compounds cannot be separated into their respective constituents by physical means. Compounds and mixtures are made up of different elements or different atoms.
Considering that scientific notation has to move the decimal over so there is only one digit in the Tens place, that is the scientific notation.
