Give a definition to the concept of “chemical equilibrium”. Do chemical reactions take place in a system that is in a state of chemical equilibrium? What is the condition for chemical equilibrium? Do the temperature, pressure and concentration of substances change in a system that is in a state of chemical equilibrium?
The reaction can proceed both forward and backward.
The state of the system, in which the rate of the forward reaction is equal to the rate of the reverse, is called chemical equilibrium. Those. in a state of chemical equilibrium, the reactions continue to proceed, but only at the same rate.
The condition of chemical equilibrium is equal rates of forward and reverse reactions and constancy of temperature, pressure and concentration. In a system in equilibrium, temperature, pressure and concentration remain constant.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
