The decomposition of phosphine, a very toxic gas, forms phosphorus and hydrogen in the following reaction: 4 PH3(g) → P4(g) + 6 H2(g). (a) Express the rate of the reaction with respect to each of the reactants and products. (b) If the instantaneous rate of the reaction with respect to PH3 is 0.34 M s⁻¹, What is the instantaneous rate of the reaction?
