What happens to the equilibrium constant of an endothermic reaction, that is in equilibrium, when the temperature increases? What would the effect of increasing pressure have on the reaction and on the value of Kc?

Increasing the temperature of an endothermic reaction would favour the forward reaction, thereby increasing the concentration of the products compared to reactants, which in hand increases the value of Kc...

2HCl (aq)+CaCO3 (s)->H20(l)+CaCl2(aq)+CO2(g). If using 40cm^3 of 2.5mol.dm^-3 Hcl and 5.67g of CaCO3, determine the limiting reagent and how much CO2(g) could be theoretically produced by this reaction.

First, we have to convert the starting measurements for the HCl and CaCO3 content into moles so we can compare the ratios to the formula. 40cm^3=0.04dm^30.04dm^32.5mol.dm^-3=0.1 moles of HClmass/molar...

What are the optimal conditions for the Haber Process N2(g) + 3H2(g) <--> 2NH3(g)? Use Le Chatelier's principle to derive your answer.

When considering the optimal reaction conditions, one must check for pressure, temperature, concentration and catalysts involved. Le Chatelier's principle states that if a change to the system is made, th...

Explain why successive ionization energies of an element increase

More energy is required to remove successive electrons from an ion with an increasing positive charge. There is large increases in ionization energy when the 2nd and 10th electrons are removed. This mean...
