The density or of carbon dioxide is 1.98kg/m^3. express the density of carbon dioxide in grams/cm^3
Explain the mechanism of action of the enzyme aconitase on citrate in TCA cycle.
The Haber process involves the following reaction
N2(g) + 3H2(g) ⇌ 2NH3(g)
N2 and H2 in the mole ratio of 1:3 were mixed in a closed container and allowed to achieve equilibrium
at 450oC. The equilibrium mixture was found to contain 15% of ammonia and the total pressure in the
container is 10 atm. Calculate the Kp of the reaction.
