Question

hello, i sent this question before but the answer you rpovided for both wasnt right and i couldnt undertstand how you got the answer. can you please show me a handwritten solution for better understanding.

1a) The decomposition of ethanol at some constant temperature (above 500°C), over a copper surface,

C₂H₅OH(g) CH₃CHO(g) + H₂(g)

was studied by monitoring the total pressure with time.
The following data were obtained:

t (s)	P_total (torr)
0	120
45	131
139	154
233	177
376	212
380	213

What will be the total pressure at t = 462 s?

1b) What is the rate constant (k)?
(Include appropriate units.)
