For which of the following reactions is the ratio kp/kc largest at 300 k?

Reaction c. has the largest value of at 300 K

Explanation:

Here is the complete question

Converting between Kc and Kp For which of the following reactions is the ratio Kp/Kc largest at 300 K?  

a. N2(g) + O2(g) ⇌ 2 NO(g)

b. C(s) +2H2(g) ⇌ CH4(g)

c. Ni(CO)4(g) ⇌ Ni(s) + 4CO(g)

d. CaCO3(s) ⇌ CaO(s) + CO2(g)

Solution

where R = molar gas constant = 8.314 J/mol-K, T = temperature = 300 K and n = number of moles of products - number of moles of reactants

For reaction a. number of moles of gaseous products = 2, number of moles of gaseous reactants = 2. So n = 2 - 2 = 0

So,

For reaction b. number of moles of gaseous products = 1, number of moles of gaseous reactants = 2. So n = 1 - 2 = -1 (we do not include the solid)

So,

For reaction c. number of moles of gaseous products = 5, number of moles of gaseous reactants = 1. So n = 4 - 1 = 3 (we do not include the solid)

So,

For reaction d. number of moles of gaseous products = 2, number of moles of gaseous reactants = 0. So n = 2 - 0 = 2 (we do not include the solid)

So,

Since for reaction c which is the largest value. So, reaction c. has the largest value of at 300 K

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
