Question

A certain reaction is second order in N2 and first order in H2. Use this information to complete the table below. Round each of your answers to 

 significant digits.

[N2]	[H2]	initial rate of reaction
1.25 M	0.267 M	3.00 x 10^4 M/s
1.25 M	0.0897 M	___ M/s
0.525 M	0.636 M	___ M/s

Answer 1

The initial reaction follows the following equation: Rate = k [H] [N]². We can plug in the given values for Rate, [H], and [N] and solve for the rate constant, k.

k = 3.00 x 10^4 M/s / 0.267 M x 1.25² M² = 7.19 x 10⁴.

Having the rate constant, you can now use Rate = k [H] [N]² to calculate the remaining two initial rates from the data in the table.
