Question 38

A nickel catalyst is used when hydrogen is added to pent-1-ene. The equation shows the reaction.

C5H10+H2→C5H12 \mathrm{C_{5}H_{10}+H_{2}\rightarrow C_{5}H_{12}} C5​H10​+H2​→C5​H12​

Relative atomic mass (ArA_rAr​): H = 1.0 C = 12.0

An excess of pent-1-ene is used with 3.0 g of hydrogen.

What mass of pentane is formed?

[1]
A

108 g

B

216 g

C

72 g

D

3.0 g
