Question

Consider the following reaction: CH. (g) + 20h (g) CO-GO + 2110 (g) At a certain temperature, 1.0 mol of CHa is consumed in 4.0 minutes. What is the rate of production of HO (In mol/min) a) 0.25 d) 8.0 c) 2.0 In a ceratin reaction the rate constant, k 1.63x10-4 M-12s. What is the order of reaction c) b) 0.50 2. )0.25 b) 1 d) 2 For a given reaction A(g) B(g), which of the following statements is correct a) Rate of reaction is the same for all concentrations of A bRate constant is the same for all concentrations of A c) Rate constant is independent of temperature d Rate of reaction is temperature independent

Explanation / Answer

Ans 1 b) 0.50

The rate of disapperance of CH4 = 1.0 / 4 = 0.25 mol / min

The rate of production of H2O is twice the rate of disappearance of CH4 as indicated in the balanced chemical reaction.

So the rate of production of H2O = 2 x 0.25

= 0.50 mol / min
