What is a substrate?
a molecule that changes state
a place where the reaction occurs
a place on the product where the enzyme fits
a reactant that is catalyzed by an enzyme

Option (d) is the correct answer.

Explanation:

Enzymes which bind with chemical reactants are known as substrate. When a substrate combines with an enzyme it results in the formation of an enzyme-substrate complex.

The reaction will be as follows.

Further, this enzyme-substrate complex upon decomposition gives product. Enzyme is a catalyst which increases the rate of reaction without itself getting consumed in the reaction. Therefore, the enzyme will remain as such.

Thus, we can conclude that substrate is a reactant that is catalyzed by an enzyme.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

can you list the answers so i can answer
