A. Equilibrium is shifted to the left
B. Equilibrium is shifted to the right
C. Equilibrium is unaltered
D. Rate reaction doesn’t change

Answer 1

Hint: During a chemical reaction, the chemical equilibrium is the condition in which all reactants and compounds remain at rates that have little additional propensity to alter over time, such that the properties of the system will not be observably modified.

Complete step-by-step answer:
Since Berthollet (1803) discovered that all chemical reactions are reversible, the principle of chemical equilibrium was developed. The rate of forward and reverse reactions is equivalent with each reaction combination.
Equilibrium occurs when the forward reaction is at the same pace as the reverse reaction. The front and reverse response speeds are typically not negative but similar. Therefore, the quantities of the reactant(s) and product(s) are not prone to net adjustments. A complex equilibrium is defined as such. Equilibrium may be commonly categorized as heterogeneous and homogeneous equilibrium. Homogeneous balance is made up of reactants and products contributing to the same process while heterogeneous balance is carried out in multiple stages with reactants and products.
The endothermic reaction is intensified by elevated temperature. The reverse reaction is an endothermic reaction in the specified reaction. The opposite reaction is thus favored, and the equilibrium shifts to the left.
Hence, option A is the correct option.

Note: The reaction rate for a specific chemical reaction is the calculation of the increase in the reactant concentration or the difference in product concentration per unit time. A change in the concentration of the material can be described as the pace of a chemical reaction divided by the period during which these changes are observed.
