Tardigrade Admin · Accepted Answer

Decomposition of PH 3 (and also NH 3 ) on the surface of tungsten catalyst are zero order reactions

Q. For the reaction, $2 P H_{3} \to 2 P + 3 H_{2}$
The decomposition of phosphine on the surface of tungsten at high pressure is

zero order

first order

second order

third order

Decomposition of $P H_{3}$ (and also $N H_{3}$ ) on the surface of tungsten catalyst are zero order reactions

Q. For the reaction, 2PH3​→2P+3H2​ The decomposition of phosphine on the surface of tungsten at high pressure is
