Rate Laws and Chemical Equilibria

The rate law for the reaction 2NO_(g) + O_2(g) → 2NO_2(g) is first order in O₂ and third order overall. What is the rate law for the reaction?

• Rate = k [NO]²[O₂]²
• Rate = k [NO]¹[O₂]²
• Rate = k [NO]²[O₂]¹
• Rate = k [2NO]²[O₂]¹

Select the order of the following figure:

• 0th order

• 1st order

• 2nd order

• Cannot be determined from the given information

Suppose I have 2 chemical reactions with different rates. I only have their potential energy curves. Select the reaction with a lower rate:

• 
• 
• Rate is equal

• Need more information

The Arrhenius law governs what relationship?

• temperature and rate constant k

• temperature and activation energy

• temperature and pH

• pH and rate constant

• The reaction is at equilibrium

• The reaction favors products

• The reaction favors reactants

• Equilibrium has equal concentration of reactants and products

• None of the above
