Please can someone walk me through how to answer this question. I’m so lost…
The rate equation for a reaction between substances A, B and C is of the form: rate = k[A]xy[C]z where x + y + z = 4 The following data were obtained in a series ofexperiments at a constant temperature. Idk which experiments to choose from or how to start it 😭
This is a "please do my homework" question. DO something first. You could also post the question the right way up! Also, this is a maths thread, try posting to Chemistry.

I will start you off...
Compare the rates of experiments 1 & 2 You will see that both concentration of A and the concentration of C do not change. So, any change in the rate is due to the change in concentration of B [B ] in experiment 1 = 0.20 [B ] in experiment 2 = 0.05
So the concentration of B in experiment 1 is 4x higher
Now look at the rate in both experiments: Rate in experiment 1 = 8.0 x 10-5 Rate in experiment 2 = 2.0 x 10-5
So the rate in experiment 1 is 4x higher
In other words the same change in concentration and rate, therefore rate is proportional to concentration, i.e. the order is 1 with respect to B
