Anoncompetitive inhibitor . binds to the active site of an enzyme a. b. increases the rate of enzyme action alters the primary structure of the enzyme c. d. none of these

 D. none of these

Explanation:  A non competitive inhibitor is the one that binds to the enzyme away from the active site.

It changes the conformaion of the enzyme as well as that of the active site.

It does not increases the rate of the enzyme action.

It doesnot alter the primary structure of the enzyme.

Thus the given options for the non reversible inhibitor are not the correct ones.

it is a solid

explanation:

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
