In a reaction that is first-order with respect to reactant A and second-order with respect to reactant B, what will happen to the rate of the reaction if we
a. double the concentration of A
b. double the concentrations of A and B
c half the concentration of A and simultaneously triple of the concentration of B
Calculate the moles and the mass of solute in 250.0 mL of 6.00 M NaOH.
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
You add 1.00 g of a solid weak acid to 100 mL of water, then titrate with 0.100 M NaOH solution. The pH at the half equivalence point is 4.22. Which of the acids in the Weak Acid Equilibrium Constant table most likely matches your unknown?
This compound sloly isomerizes completely to compund B, which has the same formula, Sketch the structures of A and B, and explain why B might be more stable than A

What must the minimum temperature of its energy source be if it is to produce work with an efficiency of 0.75?
Use an Arrhenius plot to determine the activation barrier for the reaction. Express your answer using three significant figures. (units = kJ/mol)
when 1 mole of N2 is isothermally compressed from 1 atm to 1000 atm at 0C. Find the fugacity coefficient of N2 at 0C and 1000atm. HINT: Recall that for a pure material, the chemical potential is just the molar gibbs free energy.
