Question

the combustion of ethane (c 2 h 6 ) is represented by the equation: 2c 2 h 6 (g) 7o 2 (g) 4co 2 (g) 6h 2 o(l) in this reaction: (a) the rate of consumption of ethane is seven times faster than the rate of consumption of oxygen. (b) the rate of formation of co 2 equals the rate of formation of water. (c) water is formed at a rate equal to two-thirds the rate of formation of co 2 . (d) the rate of consumption of oxygen equals the rate of consumption of water. (e) co 2 is formed twice as fast as ethane is consumed.

Answer 1

(e) CO2 is formed twice as fast as ethane is consumed.

Step-by-step explanation:

Since we have the equation of the reaction as;

2C2H6(g) + 7O2(g) 4CO2(g) + 6H2O(l)

The rate of consumption of ethene = -1/2 d[C2H6]/dt

Rate of production of CO2= 1/4 d[CO2]/dt

Hence, CO2 is formed twice as fast as ethane is consumed.
