Consider the reaction, 4 ph3(g) → p4(g) + 6 h2(g). in a given experiment, 0.0048 mol ph3 is consumed in a 2.0 l container per second of reaction. a) what is the rate of decomposition of the ph3? b) what is the rate of production of p4? c) what is the rate of production of h2? d) give three related expressions for the rate of reaction. (assume concentrations of any intermediates are constant and the volume of the reaction vessel does not change.) e) what is the rate of reaction?
