4. The decomposition of phosphine, a very toxic gas, forms phosphorus and hydrogen in the following reaction:

4PH3 (g) P4 (g) + 6H2 (g)

(a) Express the rate of reaction with respect to each of the reactants and prducts
(b) If the instanteneous rate of the reaction with respect to PH3 is 0.34 M s-1, what is the instantaneous rate of the reaction
I ALREADY CALCULATED IT BUT ITS QUITE CONFUSING.WOULD U HELP ME WITH THIS.

What numbers did you get and how did you get them?
a) Rate of rxn= (-1/4)(delta[PH3]/delta(t))=(delta[P4]/delta(t))=(1/6)(delta[H2]/delta(t))
b) Instantaneous rate of rxn= .085M/s

I'm trying to figure out how to post my answer explainations for this problem, but the website thinks that my explaination is a URL and won't allow it to be posted yet. I'm trying to get around it, if I do I will post in an additional comment!
