Given the following reaction: 2H2 (g) + O2 (g) à 2H2O (g) answer the following questions:

a. At what rate is hydrogen used in relation to oxygen?

b. At what rate is water produced in relation to the oxygen?

c. At what rate is water produced in relation to hydrogen?

2 moles hydrogen reacts with one mole of oxygen to give 2 moles of water.

a) rate of consumption of hydrogen (moles per second) is twice the rate of consumption of oxygen.

b) rate of formation of water (moles per second) is twice the rate of consumption of oxygen

c) rate of formation of water (moles per second) is equal to the rate of consumption of hydrogen.
