Question
The reaction X + Y --> products was studied using the method of initial rates. The initial rate of consumption of X was measured in three different experiments. Data are provided below.Expt [X]o
1(in mol/L) [Y]o
2(in mol/L) Initial Rate
3(in mol L-1 s-1)
1= 0.400, 0.700, 1.176
2=1.00, 0.700, 7.350
3=0.400, 1.75, 7.350
(these numbers are suppose to be in a chart)
What is the order of the reaction with respect to X? ____________ (Enter an integer.)
What is the order of the reaction with respect to Y? ____________ Enter an integer.)
Specify the units of k by giving the appropriate powers of mol, L and s:
The power of mol is ____________ (Enter an integer.)
The power of L is ____________ (Enter an integer.)
The power of s is ____________ (Enter an integer.)
Explanation / Answer
helpfull first step in the reaction is the slow step and involves the reaction of CH3COCH3 with H2SO4 to produce some intermediate. That intermediate then quickly reacts with I2 to produce the products, and to regenerate H2SO4. As long as there is any I2 at all present,
