(we want to know t to solve the problem, but we can't as we don't know D yet, therefore
we use the equation below to calculate D (as we know all the other values for this
equation that were given at the start of the problem)
D=D_(0)*e^(-(Q)/(R*T))
At 1010deg C(1283K)
D=(2.3 imes 10^(-5)(m^(2))/(s))exp[-(148,000(J)/(m)ol)/((8.31(J)/(m)ol-K)(1283(K)))]
Thus,How do I solve this equation? struggling to use the exp function. would appreciate if you could show the steps taken in the calculation.

D=Do.e-RT At 1010C(1283 K) D=2.310m/sexp 148,000j/mol 8.31J/mol-K)1283K
D=2.1510-11m2/s
Thus,
