If the temperature is increased then reaction will shift to the left because heat is absorbed.
<h3>What is equilibrium state?</h3>
Equilibrium of any reaction is that state in which concentration of reactant and concentration of product will be constant.
Given chemical reaction is:
A(g) + 2B(g) ⇄ C(g) + D(g)
From the equilibrium state reaction will move only that side which will contribute to maintain the stable state. In the forward reaction heat is released as mention in the question. So, when the temperature of reaction is increased then it shifts towards the left side by absorbing the heat and maintain the stability.
Hence, option (2) is correct, i.e. It will shift to the left because heat is absorbed.

Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
<span>Assuming ideal gas, we can label this system to follow the Boyle's Law. This Law can be applied to systems held at constant temperature. The formula used is: PV=k, where k is a constant. From the formula, P and V are inversely proprotional. So, if you graph P vs V, the graph would start from the top, then curves down towards the right. </span>
