Interpretation:
From the given options, the effect of pressure for the following reaction has to be chosen.
Concept Introduction:
Le Chatelier’s principle:
If some forces applied, the system at equilibrium will get disrupted. This change in equilibrium can be due to the change in pressure or temperature. The change in reactant concentration can also disrupt the equilibrium. Over time, the forward and backward reaction become equal and will attain a new equilibrium. The equilibrium will shifts to right, if more products are formed and the system will shifts to left, if more reactants are formed.
The principle states that if some stress is applied to the system at equilibrium, the system will adjust itself in a direction which reduces the stress.
There are four types of stress or changes which affects the system:
Concentration Changes:
Addition of reactant or product or removal of reactant or product from a system at equilibrium will affects the equilibrium. If some reactant is added to a system at equilibrium, then the equilibrium will shifts to the product side, so that the added reactant get consumed. If product is added then the equilibrium will shift towards left side.
Example:
If
If
If
Temperature Changes:
Heat is one of the products in exothermic reaction and heat is used up in endothermic reaction.
Consider an exothermic reaction;
If heat is added up, then the reaction will shift to left so that the amount of heat will decrease.
Lowering the temperature will make the reaction to shift towards right.
Consider an endothermic reaction;
Increase in temperature will shift the reaction towards right. If heat is added up, then the reaction will shift towards right.
Pressure Changes:
Only the gaseous reactants and products get affected by the pressure change.
Consider the reaction:
3 moles of reactant gives 2 moles of product.
Increase in pressure will shift the reaction towards the side which have fewer molecules.

The ether substituent is named with the suffix 'oxy'. The general format for the systematic name of a hydrocarbon is: [prefix/substituent] + [parent] + [functional group suffix] Substituents are listed in alphabetical order. Molecules with a chiral center will indicate the absolute configuration at the beginning of its name with the R and S notation.arrow_forward5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!)
